Proper usage of HASH_DEL requires that the item is known to be in the hash first. If you pass random pointers into HASH_DEL the program is going to crash. It's the same as passing a pointer into free() that's not malloc'd. Uthash does not test it for you, so if there's any doubt, you must do a lookup yourself before calling delete.
