--- Comment #6 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
The patch looks fine to me with an testcase added checking for the warning.
I sort of hoped that the type based devirt code in ipa-cp won't get into
completely contradicting answers, but that was at a time when
possible_polymorphic_call_target_p did not consider outer types, so we
definitely can construct testcases for that now.

The patch is OK if it passes testing.
