41696 - Crash at startup

Status: VERIFIED DUPLICATE of bug 41414

(Core :: XPCOM, defect, P3)

Description

[Daniel Egger]

Mozilla is sometimes crashing at startup time with random messages,
sometimes with segmentation fault and sometimes with illegal instruction.

I manage to get it working though by restarting it about 20 times.

nNCL: registering deferred (0)

Gdk-WARNING **: locale not supported by C library
WEBSHELL+ = 1
WEBSHELL+ = 2
CSSLoaderImpl::LoadAgentSheet: Load of URL 'file:
///root/.mozilla/default/chrome/user.css' failed.  Error code: 16389
CSSLoaderImpl::DidLoadStyle: Load of URL 'chrome://communicator/skin/box.css'
failed.  Error code: 16389
Ungültiger Maschinenbefehl

The last line means illegal instruction.

Unfortunately I cannot further debug it because debugging builds run
fine and the nondebug build is even crashing gdb (version 4.17.0.13 with threads
support as well as 5.0).

The crash itself is REALLY random thus I believe it's a threading problem.
I tried different things like different compilers (currently gcc 2.95.2
otherwise the latest CVS version) different linux kernels, different machines,
different locales and different glibc versions.

This bug is there for me at least 1 month now.

My normal configure options are:
--disable-debug --disable-tests --disable-mailnews

Changing them to other values doesn't help either. Optimized builds are even
more broken and debugging builds don't crash.

I'd really like to try some patch or ideas if someone steps up with something...

Moving all threading bugs to XPCOM. See bug 160356.
