I'm still getting this with media-video/vlc-1.1.12-r1.

Maybe it's one plugin that's causing the issue. Don't know if this is the problem but I get no audio via a udp stream.

[Comment 2 Chris Smith 2011-12-16 23:53:07 UTC]

the following plugins cause the seg fault here:

video_output/libxcb_glx_plugin

misc/libnotify_plugin
misc/libsvg_plugin

[Comment 4 Chris Smith 2012-01-17 00:22:08 UTC]

Same problem here with vlc-2.0.0:

>>> Regenerating /etc/ld.so.cache...
>>> Original instance of package unmerged safely.

>>> media-video/vlc-2.0.0 merged.

After a full backtrace I found that vlc-cache-gen has problems with dirac.
Solved compiling dirac without any optimization (using -O or -O0).

Does not solve it here.

[Comment 7 Chris Smith 2012-02-24 18:59:07 UTC]

what's the method to running this backtrace?

I'm using this method:
1 - emerge gdb if not

2 - cat /etc/portage/env/enable_debug.conf 
CFLAGS="-march=native -O0 -ggdb3 -pipe"
CXXFLAGS="${CFLAGS}"
FEATURES="${FEATURES} nostrip splitdebug"
USE="debug"

3 - cat /etc/portage/package.env/media-video/vlc
media-video/vlc enable_debug.conf

4 - emerge -av1 vlc

5 - gdb /usr/lib64/vlc/vlc-cache-gen
5.a - set args -f /usr/lib64/vlc/plugins
5.b - run
5.c - bt

P.S.: I'm using portage-2.2, don't know if /etc/portage/env and package.env work also with stable one.

Please try the most recent versions and see if you can still reproduce this.
