That's true here, but it's because your code is invalid :-) What happens is 
that you use CPtr<CWord1> before CWord1 is declared (except for a forward 
declaration). You see that if you try to change (for test purposes) 
CPtr<T>::~CPtr() to
        ~CPtr()
        {
                if (p)
                {
	  	  T t;
	          p->Release();
                }
        }
Then you'll get 
qparser.ii:18929: error: `t' has incomplete type
qparser.ii:18929: error: storage size of `t' isn't known
qparser.ii:18930: error: `Release' undeclared (first use this function)

(and a host of other errors later on, but this one is for T=CWord1). So change 
the order of declarations of your classes (and the use of CPtr<CWord1>) and 
it should work just fine.
