[gentoo-dev] xemacs segfault : it's not over yet

[Sebastien Phaneuf]

I'm having problem with xemacs. It's segfaulting at startup (im using Gentoo 
1.1a evrything has just been built. I did'nt run any command except for 
emerge :) ).

I browse the Gentoo archive for this probleme and a lot of people seems to 
have it. But strangely no solution has been provide...

Any Idea?

Thanks

Sebastien

See bugs 1574 and 1728.  The problem seems to lie with the sandbox
code of portage.   Hopefully, the portage wizards are working on a fix
for this bug.

Howdy,

See Comment 8 at http://bugs.gentoo.org/show_bug.cgi?id=1501

The xemacs segfaults you are seeing seem to be related to sandbox. This
is a problem that is being currently researched by gentoo developers. In
the mean time, there are two work-arounds:

1. If you have a segfaulting xemacs you can run xemacs like this to
avoid the segfaulting:

   LD_PRELOAD=/usr/lib/portage/lib/libsandbox.so xemacs

Better yet, define yourself an alias:

   alias xemacs='LD_PRELOAD=/usr/lib/portage/lib/libsandbox.so xemacs'

2. If you feel like re-emerging xemacs, temporarily change the
FEATURES="..." line in /etc/make.conf from "sandbox" to "-sandbox". Then
"emerge xemacs". The resulting xemacs binary should no longer segfault.
At this point you can restore your old FEATURES="..." line in
/etc/make.conf to include "sandbox" (a good idea).

eg. If my FEATURES line looks like:

    FEATURES="sandbox digest noclean"

then I change it to:

    FEATURES="-sandbox digest noclean"

then "emerge xemacs", then change back to 

    FEATURES="sandbox digest noclean"

Then run xemacs as you normally would (ie. no LD_PRELOAD setting
required).

I had the same problem. And procinfo segfaulted, too. I emerged and
compiled older linux kernel sources (2.4.17-r5) and the problems
vanished...

I'm trying to track down this problem myself ( because I can't live without xemacs )

Andreas, did you remerge xemacs once you recompiled the older kernel?

This is bug 1574 in bugzilla, non?

Also, in another unrelated problem ( except that it relates to xemacs ), gtk-xemacs breaks the
sandbox.

or at least that's what i assume "ACCESS DENIED open_wr:<yadda><yadda><yadda>" means.

Where's reading on sandbox available?

Yes, as far as I remember. But I did not remerge procinfo which runs
fine now.
