------- Additional Comments From pinskia at gcc dot gnu dot org  2003-10-03 02:26 -------
The shown is invalid but this valid code:
template <class T>
class Array {};

template <class T>
class IteratorImpl {};

template <class T>
class Iterator {
   public:
     Iterator (const IteratorImpl<T>* x) { delete x; }
};

template <class T>
Iterator<T> iterator (const Array<T>& t)
{
   struct Impl :  public IteratorImpl<T> {
     Array<T> _a;
     Impl (const Array<T>& a)
       : _a(a) {}
     ~Impl() {}
   };

   return Iterator<T>(new Impl());
}

Does the same ICE, this is most likely the same as bug 2513.

Might have been caused by <http://gcc.gnu.org/ml/gcc-patches/2003-06/msg02744.html> 
which is the only patch which touched comptypes during that time period.
