Don't remember. Hmmm. That sounds like it could break anyway. Can you be more specific? Also, memset the raw_node_ref to 0xdeadbeef before you free it. (Or run with slab poisoning enabled in Linux). We should go through the code and make sure manually that nothing's going to dereference a pointer to the old node after it's freed, but the poisoning is a quick and useful debugging aid. -- dwmw2
