To solve this problem I implemented an intrusive smart pointer (that calls
add_ref() and release() on the contained object.)

shared_ptr<> (or any other non-intrusive smart pointer) cannot be safely
constructed from a raw pointer (that is already owned by another
shared_ptr.) It's technically possible to maintain a global map of addresses
but I don't think it's worth it.
