Comment (by kallisti5):
Hm, this is actually one of the more interesting backtraces I've seen for
this issue. It appears that Mesa 7.9.2 crashes while allocating the
BBitmap for drawing, and Mesa 10.0.2 swrast crashes in the same spot. Mesa
10.0.2 swpipe crashes in winsys which is where our gallium renderer
allocates a BBitmap. I bet flurry is somehow passing an incorrect bitmap
size to OpenGL causing an assertions when it attempts to write beyond the
bitmap bits length.
I think it sounds like Mesa needs better checking of bitmap sizes before
writing to the bits, and flurry has some bug that exercises this issue.
