make[3]: *** [bid64_noncomp.o] Error 1

Looks like gcc got miscompiled during stagefeedback.
-march=native is amdfam10 on my machine.
Without --enable-checking=release gcc builds fine.

--- Comment #1 from Tobias Burnus <burnus at gcc dot gnu.org> ---
Additionally, check whether -fsanitize=vla-bound (are there more usans?) should
be handled.

Check whether MPX bounds checking should be implemented, cf.
