           Summary: Displist with multiple OpenGL contexts crashes.
          Severity: major
    Classification: Unclassified

          Hardware: x86-64 (AMD64)
            Status: NEW

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.

What hardware are you on? It looks like you were using mesa-9.1 -- can you try
10.0.x? I'm looking at installing blender, but it seems like Gentoo has gone
out of their way to make it a giant pain by requiring python3.3 for everything.

Can you get a backtrace, preferably with debug symbols?

Unable to repro with Blender 2.72 and Mesa 11.0.3 on either GF108 or GT215. I'm
guessing it got fixed in the intervening years.

Confirm this is fixed,

renderer:    'Gallium 0.4 on NVC3'
vendor:        'nouveau'
version:    '3.0 Mesa 11.0.3'

(tested with Blender 2.76).
