--- Comment #3 from Steven Schveighoffer <[email protected]> --- OK, I misunderstood. I thought the issue was that the red black tree itself was being pointed at, and that was causing the leak. We certainly can null pointers as the nodes are deallocated. But the tree does not go through and destroy all the nodes if you just forget the tree (and I would argue it shouldn't). So this may solve the specific use case, but not the general one. --
