You must mean shared_ptr

Actually, shared_ptr magically deals with this problem by instantiating the
deleter at the point where it takes ownership of its resource. As long as
that's on the same side of the DLL boundary where the resource was
allocated, you're golden.

It's capabilities like this, all packaged behind the interface of a single
static type, which make the design of boost::shared_ptr so powerful.
