Confirmed, here is a run-time testcase:

int t = 0;

template <typename> struct vector {

  vector() { t++; }

};



typedef vector<int> Arrays[1];

class C

{

    vector<int> v_;

    void Foo(const Arrays &);

};

Arrays a;



int main(void)

{

  if (t!=1)

    __builtin_abort ();

  return 0;

}
