New submission from Zygmunt Krynicki: It seems that a particular code sequence causes memory corruption (but not a crash so far) in the interpreter. I've attached a test case that fails assertion on python3.2 (tested on current amd64 12.04 builds) and works on python3.3 (tested on current amd64 14.04 builds and i386 fedora 19 builds).
The attached test program shows how the bug is actually triggered by using a for loop to iterate over key, value in namespace.items() inside a metaclass __new__() method that does nothing else apart from that. ---------- components: Interpreter Core files: bug.py messages: 205250 nosy: zkrynicki priority: normal severity: normal status: open title: possible memory corruption caused by for-loop iteration over namespace.items() in a metaclass defining __new__ type: security versions: Python 3.2 Added file: http://bugs.python.org/file32975/bug.py _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue19888> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
