--- Comment #11 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
The reduced testcase does not reproduce anymore so I assumed this to be fixed,
sorry for that.  The problem is that comdats pass privatizes inlined thunk.
This is bid odd side case of for_symbol_thunk_and_aliases - honestly i am not
sure if it should consider inlined thunk to be thunk anymore, but given the
name it probably should.
