I just ran it on my ThinkPad W520 (only the i915 active, the nvidia side turned off) and it didn't crash for me.. It took forever, at least 5% of the tests failed, and one test timed out, but crash it did not. Not sure what we can do on this one; if I had to guess I would say your crash must be related to the supporting libs somehow. I know we've had issues in the past with certain mesa, xorg and intel-driver version combinations.... The crash does seem to be within i965 and/or possibly mesa acording to the backtrace you posted on the upstream bug, so my suggestion would be to try different versions (latest ~arch or others in between) of xf86-video-intel and see if that helps, and then try different mesa, and maybe even different kernels. Which test does the crash occur on, do you know? Also, is this only occurring on the source-built package or does it occur with firefox-bin as well?
