Evaluating this expression causes a stack overflow, and the Python interpreter exits abnormally: eval("()" * 30000) 3.0.1, 2.6, 2.5 and current 2.x trunk all fail on Windows; the original reporter was likely using Linux. Some versions may require a larger constant instead of 30000. 2.4 isn't affected; it raises a "TypeError: 'tuple' object is not callable" as expected, even for extremely long sequences. Alberto Bertogli said: inside eval, symtable_visit_expr() (Python/ symtable.c) is called recursively (thru the VISIT/VISIT_SEQ macros), eventually taking all stack space. ---------- components: Interpreter Core messages: 86006 nosy: gagenellina severity: normal status: open title: stack overflow evaluating eval("()" * 30000) type: crash versions: Python 2.5, Python 2.6, Python 2.7, Python 3.0 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue5765> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
