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. |
