I made the change in the generated code and it seemed to work.  I had
to remove 'AnyResultBuffer' and turn the operator new and delete
functions into templates to get it to work:

   template <typename T> struct ResultBuffer {
     char _data[sizeof (T)];
     ~ResultBuffer () { ((T*)_data)->T::~T(); }
     operator T& () const { return *(T*)_data; }
   };

   template <typename T>
   inline void * operator new (size_t, AC::ResultBuffer<T> *p)  
{ return p->_data; }
   template <typename T>
   inline void operator delete (void *, AC::ResultBuffer<T> *) { } //  
for VC++

I don't know if this would affect other parts of the code or other  
compilers
though...
