Create a managed pointer that takes ownership of the object managed by the specified `alias`, but which uses the specified `ptr` to refer to its target object, unless `0 == ptr`, in which case create an empty managed pointer. Reset `alias` to empty if ownership of its managed object is transferred. The behavior is undefined if `alias` is empty, but `0 != ptr`. Note that destroying or re‐assigning a managed pointer created with this constructor will destroy the object originally managed by `alias` (unless `release` is called first); the destructor for `*ptr` is not called directly.
