open this file in blender2.66a, Press '1' key, to crash.
This is a bug we had reported in blender (3d modeling application).
But which I tracked down to being a crash in:
/usr/lib/xorg/modules/dri/nouveau_dri.so
The crash is caused by calling glCallList() when there are multiple windows
sharing the same opengl context.
(single window doesn't crash for example and removing use of display-lists in
the code also works).
I did some more tests and using Mesa-SoftwareGL doesn't crash, using NVidia
closed-source drivers.
Attached blend file to reproduce the crash, just run...
./blender displist_crash.blend
... then press ONE-Key, over either of the windows to see crash.
If you close a window before pressing ONE, it works without crashing.</pre>
