--- Comment #4 from Steven Noonan <steven at uplinklabs dot net> --- Ahh, didn't even think about an x32/ms_abi compatibility problems. That totally makes sense. It probably shouldn't work anyway, but an ICE is obviously not the right reaction from the compiler. What I should be doing is passing --disable-nine to the Mesa configure script and it will just skip the ms_abi-dependent features.
