I've had two segfaults I'd never seen before. One in sudo and one in
rdesktop. Updates later when I get things better tracked down.

I had a gcc segfault in my atom server, with MAKEOPTS=-j5. With
MAKEOPTS=-j1, I got undefined references while linking some modules.
My desktop and my laptop, however, compiled it without problems.

I haven't had the time to check it, but it seems weird.

Right now, normal emerging of anything fails for me. gdb segfaults on
spawn. Bash segfaults on spawn. I can 'sudo busybox sh', though.
Working with the guys in #gentoo-chat, figuring this thing out.

Replacing with a binpackage from packages.gentooexperimental.org got
bash working. Now I'm seeing if I can re-emerge gcc, binutils and
glibc.

If that goes through, I'm going to restart the emerge -e; my resume
stack is probably toast.

Ok, yes. This version of glibc, =sys-libs/glibc-2.14.1-r3, is crud. At
least, if you're doing parallel building. Out of my three machines,
the 8-core box got bit by it, the 4-core box got bit by it, but the
2-core laptop sailed past.

I have a hunch that setting MAKEOPTS="-j1" will fix it for me, and I'm
letting that run as I head off to sleep in a few minutes.

Note, my experiences and instructions are specific to amd64 boxes. I
don't know if other boxes are affected, and the workaround I'm writing
below is not appropriate for anything but amd64.

Incidentally, you'll know if your box got bit if you do a large set of
emerges which include building glibc, and everything after glibc's
'Install' phase fails. Don't trust emerge's output; at this point,
bash is segfaulting on startup, which makes emerge utterly unreliable,
even as it tries to tell you the cause for errors.

DO NOT close your open shells; you won't be able to launch bash until
you've fixed this.

To work around, you'll need a root shell. If you have any shell at
all, you should be able to get a root shell by running

  sudo busybox sh

in any of your remaining shells which have sudoer access.

grab

  glibc-2.14.1-r3.tbz2

from

  http://packages.gentooexperimental.org/packages/amd64-unstable/sys-libs/

using wget. At least in my situation, wget still worked. Move the
tarball to your / directory:

  mv glibc-2.14.1-r3.tbz2 /

and unpack it

  tar xvjpf glibc-2.14.1-r3.tbz2

You should now have bash back, which means you'll have emerge back,
and probably the rest of your system.

Hmm.  Been running 2.14.1-r2 since January, and 2.14.1-r3 since April

About the same here.  I'm amd64 and 4 cores running with -j10 or
something.  I have not ran a emerge -e world tho.  Sort of scared to try
it now.  :/

Wonder why some are affected and some are not?

Yeah as have I, I've even rebuilt @world since installing
glibc-2.14.1-r3 on the hardened porfile on amd64 with no problems at
all.

It's the current stable version on amd64, and you seem to be the only
one having problems with it.

I think the problem is likely with your setup (i.e. other toolchain
component, CFLAGS, ...).

Been running 2.14.1-r3 on an amd64 16-core server for a couple of weeks.
MAKEOPTS is at -j20.

No crashes so far, emerge keeps working and the machine had no problems
rebooting after a kernel update.

Checking to see if it's a distcc problem, now. If it is, it'll only be
the third time I've ever had issues from distcc, and the first time a
distcc issue resulted in a successful build of a package that broke

Just to cover all possibilities... since everyone else is saying it's
not a problem for them -- have you run a memory test?

I thought glibc doesn't use distcc even if you have it enabled.
Correct me if I'm wrong though.

Not going to be a memory issue.

1) It killed two different boxes at the same time, and one of those
has 10GB of ECC memory.
2) On the machine I can still get into, It consistently breaks each
time I emerge glibc locally, and it consistently works if I unpack the
tarball I noted from gentooexperimental.org.

OK, I got my atom server (which is amd64) to emerge glibc. The trick

Good to know. I'm still trying to figure out why emerging glibc,
specifically, breaks/broke two out of three systems for me.

I don't know what's left to try. All the libraries warned about below
are owned by glibc, and I've re-emerged binutils many times already.

Yeah, that's pretty similar to mine.

Lost my SSH session to inara (inara and kaylee are the two systems
that are borked by the upgrade, saffron is the one system I have which
upgraded without problem) when saffron hung coming out of screensaver.
I can no longer ssh into either inara or kaylee. And I won't have time
to work with either until Sunday at the earliest.

This has not been a good week.

Hey guys, I think we've pretty much established that Michael is
running into an isolated problem or some strange edge case. 
Rubbing it in further really won't help, as he is quite clearly 
having an issue with two (or three) of his boxes despite y'all's
success on yours. So can we please stop with the "works for me" 
e-mails? 

At the very least, if you were to post one such, please make it
possibly useful for Michael by including your build options and such.

Are you sure?

I remember having a lot of grief trying to graphite-ize glibc without a
swapfile. Now, every time I see glibc in the list of "things to emerge", I
swapon /.swapfile (and swapoff that file after emerge us complete).

If you're using distcc, perhaps you need to turn on swapfile temporarily on
all participating hosts.

Kaylee has 10GB of RAM...if that's not enough, I'll be disabling graphite.
(Though I haven't explicitly enabled it, either.)

But, no I'm not sure, and can't check until Sunday eveningish. Currently at
Penguicon.

Wow. Just wow. This is incredible.

This is repeatable for me.

My steps:

Start with the 12.1 LiveDVD ( http://www.gentoo.org/news/20120401-livedvd.xml )

Install latest stage 3, latest portage. Set various stuff. USE flags,
make.conf stuff, etc. Get kernel installed, reboot into system, sshd
up, etc.

Now, I essentially reused my existing make.conf file, which is at the
end of this email. I finally get to:

...and once it goes to install glibc, I get:

* The ebuild phase 'postrm' has been killed by signal 11.
 * The 'postrm' phase of the 'sys-libs/glibc-2.14.1-r3' package has failed
 * with exit value 1.
 *
 * The problem occurred while executing the ebuild file named
 * 'glibc-2.14.1-r3.ebuild' located in the '/var/db/pkg/sys-
 * libs/glibc-2.14.1-r3' directory. If necessary, manually remove the
 * environment.bz2 file and/or the ebuild file located in that directory.
 *
 * Removal of the environment.bz2 file is preferred since it may allow the
 * removal phases to execute successfully. The ebuild will be sourced and
 * the eclasses from the current portage tree will be used when necessary.
 * Removal of the ebuild file will cause the pkg_prerm() and pkg_postrm()
 * removal phases to be skipped entirely.

So, once the updated glibc goes in, anything that dynamically links
against it fails on spawn, hence the failure at postinst. This is
crazy.

Can you upgrage to glibc-2.15?
Can you tweak you gcc flags to something more conventional and see if the
problem persists?
If you are interested in submitting a patch to the upstream then you can build
the glibc test suite with your gcc flags and check if the tests pass.

Sure. It's going to be another full reinstall.

Those CFLAGS should be equivalent to:
CFLAGS="-O2 -pipe -ggdb3 --march=native".

But I'll try making it just -O2 -pipe --march=native.

If it gets things fixed. I have two machines which have been offline

It updated gcc immediately before glibc, IIRC, so I expect it's newest
stable. Kaylee is offline until I do a new reinstall again, but it
looks like latest stable in portage is 4.5.3-r2.

I do still have a working gentoo laptop I could try this on...but it
has an i3 proc, as opposed to the core 2 xeon or the phenom 9650. Have
a link to instructions?

For anyone following or interested, this is now reported as bug
#423149. I'll be tracking progress there, so I have a common place to
keep notes and discoveries as I try to work it out.

As it turned out, it was my CFLAGS. Not the ones anyone usually cares
about, either.

If you build glibc with CFLAGS="${CFLAGS} -g3", your glibc will be
very, very broken. Apparently, it's old, known and has been a problem
for about five years.[1]

Which means that when I changed my CFLAGS from "-ggdb" to "-ggdb3" a
few months ago, the next time I emerged glibc was going to be the time
that killed my system. I didn't think twice about it at the time,
either; When trying to debug something, how often does it turn out to
be the debugging *data* that's causing the problem? I'm accustomed to
systems behaving differently with debuggers attached, but this
was...bizarre.

The other big thing I kept hearing about was "try changing
{this|that|other thing}; it might be affecting glibc, because glibc is
a whiny b*tch". Are there alternatives to glibc?

Meanwhile, while trying to accelerate the tweak/retry cycle of testing
this, I wrote a script which automatically installs, configures,
updates and builds Gentoo. I'll share it on github soon enough; it's
got a bunch of pieces which are particular to my use case. Just a
couple more changes before it generates a clean, configured system
(for me). Once I've got a stable, working box at home, I'll be able to
refine it.

Alternatives? Hardly, I think. There are some "lightweight" variants:

- - sys-libs/uclibc
http://www.uclibc.org/

- - dev-libs/dietlibc
http://www.fefe.de/dietlibc/

comes to mind, but afaik they don't have the full functionality of
glibc. uclibc seems to be enough for XFCE, though (there is a hardened
stage4 with XFCE named lilblue made by blueness)

Thisd sounds worthy of a bug report, an ebuild allowing you to break
something as critical as glibc without even a warning does not sound good.

Take a look at my bugreport: https://bugs.gentoo.org/show_bug.cgi?id=423149

And then follow through to the bug report it was marked as a duplicate
of. Gentoo devs, at least, know of the problem, but don't want to put
a workaround in the ebuild for it.

Also, even if the ebuild issued a warning, there's no guarantee the
warning would ever be made visible; the system is well and truly hosed
before the 'postinst' stage of the install, so who knows whether or
not the cache-and-show-later warnings would reach the user?

There is a facility for an ebuild to check things like this and override
them or refuse to continue, unless you set $I_KNOW_WHAT_I_AM_DOING.

I'll file an enhancement request against the ebuild tonight. (I hope,
