--- Comment #6 from Martin Jambor <jamborm at gcc dot gnu.org> ---
Fun fact, for me the benchmark passes (test) verification when built with:
  -O2 -g -flto=16 -fno-ipa-sra

but fails when built with:
  -O2 -g -flto=16 -fno-ipa-sra -fdump-ipa-all

Consistently so.  On revision r12-5309-g0002a8a1997c7b.

I thought I was going mad when attempting to somehow isolate what was
going on.  But I do not really know what to do with this piece of
knowledge.
