struct S

  int i;
};

template<int S::*p>
struct X
{
  X ();
  X(const X<p> &);
};

template <class T>
struct Foo

  }
};
------------------------------------------
test.cc:18: internal compiler error: Segmentation fault

I think this is another fallout of two-stage lookup so it should be 3.4/3.5 
regression, but can anybody please test this on the 3.3 branch? It works with 
3.2.2.

Kriang, I'm CCing you because it might be related to the other segfault you 
fixed in convert_nontype_argument (it's still a SCOPE_REF with no type 
computed).
