Armin Rigo <ar...@users.sourceforge.net> added the comment: 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 :-( ---------- nosy: +arigo _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue14010> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
