struct Func

  struct Value : public F<T> {};

template<typename X>
struct First {
  template<typename Y>
  struct Res_ {

  typedef Func<Res_> Res;
};

int main()
{
// this lines produces an ICE
  typedef First<int>::Res::Value<float>::Res a;
// with the following line, it compiles properly
//typedef First<int>::Res_<float>::Res a;
}
>How-To-Repeat:
just compile
