This looks like a memory corruption in host compiler. Could be a compiler bug or hardware bug. bug #667032 looked similar on sparc and happened to be very non-deterministic.

If your bug is reproducible please extract preprocessed file using https://wiki.gentoo.org/wiki/Gcc-ICE-reporting-guide.

If it's not reproducible then running single gcc command in a loop might allow triggering the problem in a somewhat reproducible manner.

If it's not reproducible even then it's worth checking the hardware.

I'm trying a second time, I'll close the bug if it succeeds.

Indeed seems to be a hardware problem.
