- The RtlEnumerateGenericTableWithoutSplaying function in RTL (generictable.c) effectively performs an endless enumeration, never advancing to the next successor element in the tree because of a bug in the code. Fix this. (Bug #3756).
- The RtlDelete code misses a line of code checking whether the node is a root,
and instead always returns NULL (assuming it is the root). Fix this. (Bug #3760).
See issue #3760 for more details.
