The following code causes an assertion in name mangling:

  template<typename T>
  struct supermeta {
    template<typename U>
    struct apply {
      typedef T U::*type;
    };
  };

  struct X { };

  template<typename T, typename U>
  typename supermeta<T>::template apply<U>::type f();

  void test_f() {
    f<int, X>();
  }


Assertion failed: (TD && "FIXME: Support dependent template names"), function
