Thanks for trying!

hmm, are you testing with X with DISPLAY set? (I test with Xorg & mutter
started manually)
Then:
DISPLAY=:42 ./piglit run -t
".*arb_blend_func_extended-fbo-extended-blend-pattern_gles2" -o -v
tests/quick_gl results/quick_gl
Will crash qemu in i965_dri.so:

I can try to get a better backtrace.</pre>
