--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Reduced testcase:
template<int VALUE>
struct Outer
{
  struct StupidValueTrick
  {
    template<int VAL> friend struct Outer::StupidValueTrick;
  };
};
typedef Outer<42>::StupidValueTrick GoodValue;
GoodValue good;
---CUT ---
Confirmed.
