--- Comment #5 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
This is yet another case where get_binfo_at_offset incorrectly returns NULL
(wich is in there for long time, but before we started sanity check it just led
to missed optimizations).
In class D there is base C7 and A (that is virtual base of C). They share vtbl
pointer, but get_binfo_at_offset is organized in an assumption that sharing of
pointer doesn't happen over sibling bases.
I guess easiest fix would be to recursively dive into all bases with a given
offset, but I will try to look through C++ FE implementation first to see if
there is more elegant way around.
This may affect ipa-devirt, too, that may need to push vtable into the stack
even in the sibling walk.

This is probably because I commited the fix to mainline only (GCC-5), I will
backport
