--- Comment #5 from Sam James <sjames at gcc dot gnu.org> ---
>From my overnight run, just for completeness:
```
struct a {};
template <int> using b =3D a;
template <template <typename> class, typename, typename> using c =3D a;
template <typename g> using d =3D g;
template <class> constexpr int e(b<1>) { return 1; }
template <class f> struct o {
  void operator=3D(o) noexcept(e<f>(c<d, int, b<1>>{}));
};
template <typename, typename, typename> using h =3D o<int>;
template <typename i, typename j, typename k =3D i> using l =3D h<i, j, k>;
l<int, int> m, n;
void p() { m =3D n; }
