With set hook this is ref to temporary variable (default_rbtree_node_traits_impl::get_parent returns value). With any hook this is ref to node's variable (any_rbtree_node_traits::get_parent returns reference). This variable is used after node changed. Use local var? PS: are other rotate_XXX functions OK?"
