Hmm, I can't quite remember the whole context of that discussion.
However, I know that my code works (with g++ at least, not MSVC, mind you).
My factory function returns an auto_ptr<X>, where 'X' is the type being
exported via class_<X>. If yours returns a raw pointer, you may need
to specify a return_value_policy, or wrap with boost::python::ptr() to
give a hint at how you'd like the memory to be managed.

HTH,
