I see this a lot, gcc is miscompiled (I think it happens in dse.c) and a
bitfield operation with index out of bounds happens, which causes the SIGILL.

This is one of the reasons default optimization flags are -O1 currently, when
building gcc with -O2 it dies a lot more due to this issue.

I can reliably trigger it by trying to build tcsh from pkgsrc.
