Bug 546474

Created attachment 377618 [details]
File: backtrace

i can´t reproduce this because it works on my system.
Please update your system an test it again.

The system is fully updated to the latest updates/updates testing. I guess it can be related to the some kind of pulse audio problem as nearly all games from LGP throws ALSA lib pcm.c:2171:(snd_pcm_open_conf) Cannot open shared library /usr/lib/alsa-lib/libasound_module_pcm_pulse.so error and there is no sound in them. It worked around beginning of Dec.
Any idea what should I try?

BTW under root:

I see this on a fully updated F12 system.  It appears to be the cause of various other programs crashing as well.

Actually there must be an underlying issue, but I can't tell what it is.  Partly due to so much optimization that it's impossible to read the important variables and also because the top of the stack is either corrupted or has no debuginfo.  I installed every debuginfo package it suggested and the top of stack is still:

#0  0x00158450 in ?? ()
#1  0x05f71fee in stream_get_timing_info_callback (pd=<value optimized out>, command=<value optimized out>, tag=<value optimized out>, 
    t=<value optimized out>, userdata=<value optimized out>) at pulse/stream.c:1731

I see this exact same signature on my warzone2100 crash.

The relevant line is:
1730	    if (o->stream->latency_update_callback)
1731	        o->stream->latency_update_callback(o->stream, o->stream->latency_update_userdata);

On further testing, there is no consistency.  It really looks like memory corruption somewhere.  Here's another stack from openal-info:

#0  0x0011a4f8 in ?? ()
#1  0x0011b041 in ?? ()
#2  0x0804dc20 in ?? ()

Backtrace stopped: frame did not save the PC

Sometimes openal-info prints some info before it crashes:

$ openal-info
Available playback devices:
    ALSA Software on default
    OSS Software
    PortAudio Software
    PulseAudio Software
Segmentation fault (core dumped)

It's always the same, either that output or nothing.

I will build an newer version of openal-soft when pulseaudio 0.9.22 is ready because in pulseaudio 0.9.22 is an bug fixed with openal-soft.

Yup, this update fixed this bug for me, what about others?
