Message #5 received at submit <at> debbugs.gnu.org (full text, mbox):
When editing a file in emacs in GTK mode, emacs reproducibly crashes for
me. It doesn't happen when start editing with 'emacs -nw'.
One example test case where this reproducibly happens for me on
NetBSD-6.99.23/amd64 is
emacs /usr/pkgsrc/doc/guide/files/options.xml
It also happens with
emacs -Q /usr/pkgsrc/doc/guide/files/options.xml
but not with
emacs -nw /usr/pkgsrc/doc/guide/files/options.xml
When I compile emacs with '-g -O0' and start it in gdb, I get the
following backtrace (bt full):

From that description it'd be a bit painful for me to try to reproduce
the problem, as I don't use NetBSD and don't know where to get
NetBSD-6.99.23/amd64's /usr/pkgsrc/doc/guide/files/options.xml.
Is that file easily retrievable from somewhere?
I could try to reproduce the problem with the Emacs trunk
on platforms that I use.

Another detail I just noted: the core dump only happens for me when
the emacs window first gets focus.

Just to make sure: you were using a gtk version of emacs?
Which version of gtk do you have installed? Perhaps that makes a difference too.

Ok, I'm still using gtk2. I'll try and compile it against gtk3.

Ok, I've now tried with an emacs compiled against gtk3-3.8.2 and still
see a core dump. So perhaps it is NetBSD-specific.
I've included a detailed core dump in my original bug report.
Does anyone have an idea what could be the cause?

Looks like a bad pointer.
If it's easily reproducible, can you reproduce it under valgrind?
I'm attaching the valgrind.supp I use on Fedora 17, maybe you can
use something similar on NetBSD. It works only with temacs, but
perhaps you can reproduce the problem with temacs. Instructions
for use are near the start of the attached file.

Sadly, there is no valgrind port for NetBSD. Do you have another idea
how to track this down?

Sorry, I've never used NetBSD so I don't have
any ideas other than "run GDB and tear your
hair out".

Some minimal progress:
# emacs creating.xml

So there seems to be some big object on the stack.
What are your stack size settings?
Can you reproduce this segfault by reducing your stack size?
Suggestions where to look?
Thanks,
Thomas

No, it works for me with Fedora 19 x86-64
and Emacs 24.3 (bundled with fedora)
even after I type 'ulimit -s 4096'.
It works even after 'ulimit -s 1024'.
Sorry, I don't know what to suggest next,
other than GDB.

Valery Ushakov <uwe <at> stderr.spb.ru> tracked it down.
It was a bug in the environ variable handling in NetBSD's libc that
interacted badly with emacs' loading/saving of environment states.
See the thread on NetBSD's current-users mailing list; perhaps start
reading at
http://mail-index.netbsd.org/current-users/2013/09/08/msg023271.html
where Valery starts getting into details.
A fix was committed to NetBSD-current; I think the bug appeared after
NetBSD 5 and before NetBSD 6.
You can close this bug report. Thanks for your help!
Thomas
