--- Comment #26 from Jonathan Wakely <redi at gcc dot gnu.org> 2011-06-02 21:29:53 UTC --- (can this bug be un-ASSIGNED?) (In reply to comment #25) > Here, H must have a virtual destructor. The point where it can know it should > warn is the "delete this;" line. I've posted a patch to http://gcc.gnu.org/ml/gcc-patches/2011-06/msg00191.html which gives this for the code in comment 25 7302.cc:16:12: warning: deleting object of abstract class type ‘H’ which has non-virtual destructor will cause undefined behaviour [-Wdelete-non-virtual-dtor]
