Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Doesn't ICE starting with r239267 anymore. struct A { constexpr A (int); constexpr operator int () const { return 0; } int c; }; template <int> struct B {}; constexpr A a = 0; B<a> b; still ICEs though.
