--- Comment #4 from Patrick Palka <ppalka at gcc dot gnu.org> ---
Reduced testcase exhibiting the latest ICE:

$ cat 103994.H
template <typename> struct TransparentSupport {
  template <typename> using key_arg = int;
};
template <typename Key> struct Map {
  template <typename LookupKey>
  using key_arg = typename TransparentSupport<Key>::template
key_arg<LookupKey>;
};
struct MapKey {
  Map<MapKey> map_;
};

$ g++ -fmodule-header 103994.H
103994.H: internal compiler error: in insert, at cp/module.cc:4924
