I agree with your sentiment, but I doubt those problems I identified are
causing SIGBUS errors. They will either cause the build to fail, or,
perhaps, cause the timing information to be less useful.
Still, it's plausible that some other bug elsewhere is now getting tickled
in a way that it wasn't before. If r41087 can be made to fault fairly
consistently, and r41080 (or whatever) can't, then that is indeed
meaningful data.
