with -Ofast -march=native -flto
Product: gcc

Our Aarch64 benchmarker (armv8.2-a+crypto+fp16+rcpc+dotprod+ssbs)
signals that SPEC 2006 434.zeusmp segfaults at run-time when built
with -Ofast -march=native -flto and master revision
r14-7022-g34d339bbd0c1f5.
Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

Unfortunately at the moment don't have another access to another
adequate Aarch64 machine to debug further and so I cannot provide more
information (and so the component "target" is likely bogus, sorry).
