[gentoo-amd64] Anyone else running the KDE 3.5-rc1? Trouble with kmail?

[gentoo-amd64] Anyone else running the KDE 3.5-rc1? Trouble with kmail?

[Duncan]

kmail-3.5.0-rc1 crashes when trying to retrieve POP3 mail, here.  If
there's no mail to retrieve, it's fine.  The crashes have resulted in a
number of different messages to a konsole used to invoke kmail,
including sig-11/segv, sig-6/abrt, and an error having to do with
mime/base64 decoding, something about an inline pad character encountered.

Reverting (using emerge --nodeps to keep from reverting a bunch of other
stuff) to kmail-3.5.0-beta2 got me up and working again, with no issues.

Other unstable/testing-masked packages here, that may play a part:
glibc-2.3.6, gcc-4.0.2 and associated binutils updates.  -beta2 was
compiled with gcc-4.0.2 and the newer binutils, and works fine, however,
so that isn't it unless there's an issue with a code change between
kmail beta2 and rc1.  glibc could be implicated, however, as I was running
a 2.3.5.2005mmdd snapshot until just before I did the rc1 compile.  (I had
started the rc1 merge, but had issues with unfound tarballs, so resynced,
and the glibc update came in with the resync as well as the kde ebuild
unfound tarball issue resolution.  Yes, I ran into the glibc symlink issue
but fortunately was able to resolve it and that's another story anyway.)
glibc-2.3.6-rc1 is available for merge according to portage, but I've not
merged it yet.

Hi,
I am using 3.5-rc1 and had not one crash so far. Not one KDE app crashed.

I am using Kmail pretty much, with 100+/- some douzend emails a day and it 
just works.

I have glibc2.3.6, but I am using gcc 3.4.4

So I would suspect some miscompilation by gcc4 ... there are some reasons, 
that it is still hardmasked ;)

Yes, but usually it's simply that it's stricter and therefore refuses to
compile whatever.  Additionally, KDE 3.5 is supposed to be gcc-4.x tested
upstream, as they are doing the gcc-4.x fvisibility stuff that had to be
pulled from kde 3.4.whatever.

Never-the-less, thanks for the datapoint!  It could well be that this
isn't one of those "usually" things.  =8^\  Now that I know it works for
you with glibc-2.3.6, and gcc-3.4.x, I can eselect compiler to 3.4.4 and
recompile, to see if that fixes it.  If I can trace it, perhaps filling a
bug upstream may be appropriate.

Everything else seems to be working great, including one thing I had a
problem with in beta2!  =8^)

I /did/ try temporarily turning off my filters, of which I have a decent
number, and that fixed it temporarily, but turning them all back on caused
another crash the next time I had mail to fetch.  Thus, it's also possible
it's due to some strangeness with my filters, and tracing the individual
filter and redoing it might solve the issue.  Again now that I know it's
working fine for you gives me reason to investigate further, since I know
it's not something everyone's running into.

Seems I have some testing to do, now that I've confirmed both that and
that I can revert to my bin-packaged beta2 version once a day or so to
get the collected mail.  Again, thanks!

hm, very intersting, but the gcc is the only difference.  Hm, or is it the 
binutils?
I have 
sys-devel/binutils
      Latest version available: 2.16.1
      Latest version installed: 2.16.1

hm, for me, kde 3.5-beta2 and rc1 are even more stable than any other release 
ever.

I had not one crash or misbehaviour so far - which is very promising. 

But if you want to recompile with ggcc3.4 don't you need to recompile qt and 
kdelibs too?
I am not sure, but prior experiences with 3.2 and 3.3 told me, that 
kdepackages can be pretty annoying if not compiled with the exact same 
compiler.

Glück Auf

sys-devel/binutils
      Latest version available: 2.16.91.0.1
      Latest version installed: 2.16.91.0.1

I'm not sure if it's still hard-masked or if it is now ~arch, but it was
hard-masked when I overlayed and keyworded it, as it was a dependency of
the (also still hardmasked) gcc-4.x.  That's what I met when I said
"related" binutils -- I had to unmask both (tho I had a choice of possible
binutils versions to unmask and merge) to get gcc4.

The beta2 thing wasn't major.  It was xmms-kde, a kicker applet to control
xmms/noatun/xmpeg.  It would launch sometimes, but not others, complaining
about a library it couldn't find.  Actually, now that I think about it,
the problem and why it now works was probably that I needed to run
fix_libtool_files.sh, and did so after the -rc1 merge died shortly after
initial run.  After running fix_libtool_files.sh, the merge finished. 
xmms-kde probably had a dependency on something configured with an la file
that pointed to a stale gcc version, so running the script fixed it as
well.

Well, the major problem, is libstdc++.  The gcc-4.0 versions are supposed
to be generally backward compatible with the 3.4 versions, and I've found
it to be generally so.  There are occasional issues, but they are usually
fixable if one can find the correct combination of 3.4 and 4.0 compiled
applications and libraries.  Running fix_libtool_files.sh and recompiling
the target application often helps, as was apparently the case with
xmms-kde, but to do that, you have to know which specific version is
causing the error, so you can run it against that version.  This of course
isn't a big issue with binary distributions where everything in a release
is compiled using the same gcc, thus against the same libstdc++.

You are correct, however, it can be "annoying", at times.

FWIW, I'm now running a gcc-3.4.4 compiled kmail, and no problems yet, but
I've only had a few spams come thru since I restarted it, so I can't say
the problem's definitely fixed.  So far tho, so good (said the guys
jumping out of the twin towers as they passed the 10th floor, hopefully
this experience ends rather better, and hopefully noone finds this in
/too/ bad a taste).
