Comment:

 When working on another ticket, I realized that replacing the use of
 `auto_ptr` with `shared_ptr` to manage the `Impl` pointer member of the
 `Rdata` class is not possible as the `Impl` pointer is an opaque type in
 the headers (will not work with `scoped_ptr` and `shared_ptr` in those
 locations).

 So we can close this ticket as invalid.
