You can try to build xorg-server with CFLAGS="-g" and get a backtrace according to http://www.x.org/wiki/Development/Documentation/ServerDebugging And please report this also upstream at https://bugs.freedesktop.org/
Created attachment 362600 [details] gdb full backtrace
Could you try 2.99.905-r1? It has the patch from the upstream bug.
(In reply to Rémi Cardona from comment #4) > Could you try 2.99.905-r1? It has the patch from the upstream bug. That fixes it for me.
Closing then. Thanks
