Well, I think gfortran 4.5 just silently produced wrong code, and then
Michael's patch triggered the ICE (uncovering a bug that had been there
before).

The dump with my patch shows

      D.1574 = D.1572->_data->a_type.length;

while 4.5 gives:

      D.1565 = D.1563->$data->length;

(missing the "a_type" parent reference).
