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?
http://lists.freedesktop.org/archives/mesa-dev/2011-January/004888.html

Doesn't seem to happen with llvmpipe fwiw.

Probably a duplicate of bug 31940.

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.
