In addition to Neils points: Code like this: shared_ptr<Node> node(new Node); Node* rawNode = node.get(); shared_ptr<Node> nodePointerWithDifferentReferenceCountObject(rawNode); This will end up with two different reference count instances for a single object instance. Note that this kind of usage pattern happens quiet often in osg ... ... think of adding nodes to a group and adding the same node to an other group and many more.
