full backtrace

When running WebGL test runner with r300g there is:
Program received signal SIGSEGV, Segmentation fault.
0x02650ab3 in dri2FlushFrontBuffer (driDrawable=0xb0e91200, loaderPrivate=0xa2afb020) at dri2_glx.c:460
it doesn't always crash at the same test but it is 100% reproducible when you click run tests and wait.

This is with 
mesa: d136d1d2e1174d2420ce5e32507904243ab240cd
kernel: 2.6.37
GPU: RV530
Firefox 4.0b8

Firefox must be started with MOZ_GLX_IGNORE_BLACKLIST=1 (acceleration is disabled by default for mesa because of crashes). You also need to set webgl.enabled_for_all_sites to true in about:config. I'll try to reproduce this with some other driver.

I guess this is the same bug as mentioned here?

Doesn't seem to happen with llvmpipe fwiw.

Probably a duplicate of bug 31940.
Comment 3 Alex Deucher 2011-01-17 07:57:11 UTC
Can you try the patch on bug 31940?

Patch from bug 31940 doesn't help.

Closing as duplicate of bug 37253 because that other bug has more specific information.
