The issue is a stack exhaustion.  Examples can be trivially made for any iterator that takes another iterator as argument: itertools.takewhile(), zip() in Python3, etc. etc.

It's just one of many places where CPython does a recursion without checking the recursion depth.  CPython still works, based on the resonable assumption that doing such a recursion here is obscure.

Someone seriously bored could start with some C-based callgraph builder; or alternatively use PyPy, which finds such recursions automatically in its own source, and compare all places where a recursion check is inserted with the corresponding place in CPython.  There are a large number of them (761, not counting the JIT), so be patient :-(
