--- Comment #16 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Created attachment 37965 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=37965&action=edit gcc6-pr70147-2.patch As the compromise I meant this instead (incremental patch). Though, in that case the -flifetime-dse=2 clobbers are also wrong in the subobject ctors, because they should not overlap the vtable pointers of the virtual bases if we rely on them from the caller, otherwise when those are inlined could be DSEd, even when we actually rely on them.
