--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
template <bool> struct A;
template <typename = int> struct B;
struct C {
  template <typename> static int c ();
};
template <class T> struct D : C {
  using c = decltype (c<T>);
  using E = typename A<c::g>::E;
};
D<B<>> g;

Without -g this is a accepts-invalid.
