--- Comment #5 from Martin Sebor <msebor at gcc dot gnu.org> ---
The ICE can be avoided by using a struct instead of a template alias:

template <int> struct ops {
  template <int> struct A;
  template <int *Ptr> struct explode {
    typedef typename A<*Ptr>::join type;
  };
};
template <typename Ts> typename ops<'\0'>::explode<Ts::join>::type a;
