--- Comment #12 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
With that reduced testcase, I've bisected it to r208831, before inlining pass
there are no differences, and starting with r208831 the inliner changes
3 calls to __builtin_unreachable - __dynamic_cast, AWindow2::isParent and
fwrite.  Haven't yet looked why the inliner considers those unreachable, if
there is some undefined behavior that makes those unreachable, or something
else.
Honza?
