I didn't notice before, but the failures contain stack dumps. It looks like llvm-mc is crashing on those tests, but only the stage2 llvm-mc.

It is our only self-hosting i386-linux tester.

Rafael, is the ELF writer used when running llvm-mc on Linux? That might explain why it is only failing on Linux.
