Yes, this is a classic tree traversal. Assuming the tree isn't
broken, the loop eventually terminates when it runs of a leaf.

The real issue with this code is that this is the *only* exit
condition of the loop. The traversal loop always branches until
it hits a leaf and the function then returns NULL. I'm pretty
sure this might not be the intended behavior.
