New submission from Thomas Heller <[EMAIL PROTECTED]>: The following code, which only works on Windows, crashes with an access violation somewhere in the garbage collector in a debug build:
>>> import _ctypes [43470 refs] >>> _ctypes.COMError(1, 2, 3) The problem is that the PyComError_Type's tp_flags contains Py_TPFLAGS_HAVE_GC although the tp_traverse slot is NULL. The attached patch removes the Py_TPFLAGS_HAVE_GC which is not necessary at all because a PyComError_Type instance (normally) only contains simple objects (strings, numbers, None, and a tuple of strings, numbers, and None), so no reference cycles should be possible. ---------- assignee: theller components: ctypes files: ctypes.patch keywords: needs review, patch, patch messages: 76451 nosy: theller priority: release blocker severity: normal status: open title: _ctypes.COMError crash type: crash versions: Python 3.0 Added file: http://bugs.python.org/file12133/ctypes.patch _______________________________________ Python tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue4433> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
