eryksun added the comment: In Py2Reg, the REG_BINARY (3) case sets `*retDataSize = 0` when the value is None:
http://hg.python.org/cpython/file/04f714765c13/PC/winreg.c#l766 It doesn't modify *retDataBuf. Then in PySetValueEx, PyMem_DEL is called for the uninitialized address in data: http://hg.python.org/cpython/file/04f714765c13/PC/winreg.c#l1566 Py2Reg in this case could also set `*retDataBuf = NULL`. RegSetValueEx allows lpData to be NULL when cbData is 0. http://msdn.microsoft.com/en-us/library/ms724923 ---------- nosy: +eryksun _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue21151> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
