--- Comment #6 from Patrick Palka <ppalka at gcc dot gnu.org> ---
ICE-on-valid version:

template<class> struct Visitor_functor;

template<> struct Visitor_functor<int> {
  using type_t = int;
};

template<class T> struct Events {
  template<class Fn=T> struct Visitor {
    Visitor_functor<Fn>::type_t t;
  };
};

using ev_t = Events<int>;
ev_t::Visitor v = { {} };
