Seems to be related to templates.  Test case: 
 
template<class type> 
class foo { 
  private: 
    int size; 
    type *a; 
 
  public: 
    foo<type> (int max) { 
      size = max; 
      a = new type[size]; 
    } 
 
    type& foo<type>::operator[] (int index) { 
      if (index > size) 
        index = size; 
      return a[index]; 
    } 
}; 
 
int test (void) 
{ 
  foo<int> bar(2); 
  bar[1] = 1; 
} 
 
gives, 
CPROP of ~PtO^HØ , pass 1: 2304 bytes needed, 0 const props, 0 copy props 
BYPASS of ~PtO^HØ : 3 basic blocks, 2304 bytes 
etc.
