Hello, i have an issue with Skype lately (i compile mesa, kernel, drm, xserver from git periodically and i use a A8-6500 with its IGP with r600g and glamor). It crashes the x server if i use bi directional video call. It seems to work in one-way video. The x server restarts, but skype continues to work for about half a minute more, including sending video. One problem is that i dont see any errors in any logs, not dmesg or xorg log so i cant say which component is the culprit.
Now it seems that a similar issue existed in the past and it was related to some drivers that couldnt handle multiple xv instances (one for the received video, the other for the local video thumbnail). And there was a workaround of disabling the local video thumbnail which cant be done on the current Skype (4.3). The glamor xv reports 16 available ports though.
Is there any other way of diagnosing this error? Maybe i have some issue with the 32 bit driver installation? Although i had no problems whatsoever (gaming on Steam, vdpau etc works well for example) other than this.
Attach gdb to the xserver and get a backtrace when it crashes. Make sure you install the debug symbols for the xserver, etc. http://www.x.org/wiki/Development/Documentation/ServerDebugging/

I idd a bdb trace a while back and it does seem incomplete probably because something wasnt compiled with debug on.
Program received signal SIGABRT, Aborted. 0x00007f530e3d5077 in __GI_raise (sig=sig@entry=6) at ../nptl/sysdeps/unix/sysv/linux/raise.c:56 56 ../nptl/sysdeps/unix/sysv/linux/raise.c: No such file or directory. Continuing. [Thread 0x7f53083d7700 (LWP 32676) exited]
Program terminated with signal SIGABRT, Aborted. The program no longer exists.
Anyway, the cause is clearly glamor on r600g related as i have disabled glamor and on exa i did not have any such issues. Even with the newest xserver git build it does crash nonetheless.
The question is whether the issue is in glamor or r600g or mesa.
