Test case for incorrect reference counting

RcName is a struct that defines postblit, this(this), in order to implement reference counting. When I store the result of a call and then return it:
  RcName rc = create();
  return rc;
I get the right reference count. But if I return directly:
  return create();
postblit is called (increasing ref count), but the destructor is not, so I end up with ref count that is too big
