--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> --- That is just weird. Yes, the patch changes the lookup rules for the dtors, so in some cases there will be a placement operator delete call if exception is thrown from constructor of a placement new, in other cases there won't be one where there was one before, but in most cases placement operator delete just does nothing. I'd really like to see a preprocessed source where it makes any measurable difference...
