As you can tell, I have problems remembering whether that function name has
a final "s" or not...
The stack overflow looks like some simple error in the recursion, or it
might be due to a cycle in the data. Programming tree traversals is a lot
more complicated if you have to check for cycles as you go. (And the example
in my book that attempts it is embarrassingly wrong.)
