Here is a small testcase: 
-------------------------- 
struct S { 
    S (); 
    void reinit (); 
}; 
 
struct P { 
    P & operator= (S *); 
    S * operator -> () const; 
}; 
 
class X { 
    void reinit (); 
    P p; 
}; 
 
void X::reinit () 
{ 
 p = new S(); 
 p->reinit (); 
} 
-----------------------------
