--- Comment #4 from Jan Hubicka <hubicka at gcc dot gnu.org> --- OK, this is ICE on type inconsistent program (it looks up virtual function in non-virtual type). I forgot gcc_unreacable on that code path from earlier sanity checking. I will arrange such inconsistent calls to be builtin_unreachable.
