--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> --- (In reply to Jakub Jelinek from comment #4) > That is still too big, here is a smaller one: > struct B { virtual unsigned f () const; }; > struct C { virtual void f (); }; > struct F { virtual unsigned f (bool) const; ~F (); }; > struct J : C, F {}; > struct G : J { unsigned f (bool) const { return 0; } }; > struct H : B > { > H (int); > unsigned f () const { return ((const F &) h).f (0); } > G h; > }; > H h (0); Though, on this reduced testcase the ICE started with r176424, i.e. making it a 4.7/4.8/4.9 Regression on that testcase.
