New submission from Isaac Elliott <isaace71...@gmail.com>: python3's parser stack overflows on deeply-nested expressions, for example:
[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]] or aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa(aa())))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))) These are both minimal examples, so if you remove one level of nesting from either then python3 will behave normally. ---------- messages: 314485 nosy: Isaac Elliott priority: normal severity: normal status: open title: Parser stack overflows versions: Python 3.6 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue33149> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
