(from msg244587 in issue16991)
Coverity has found an issue in odict, too:
*** CID 1302699: Null pointer dereferences (NULL_RETURNS)
/Objects/odictobject.c: 1316 in odict_copy()
1310 od_copy = PyObject_CallFunctionObjArgs((PyObject *)Py_TYPE(od), NULL);
1311 if (od_copy == NULL)
1312 return NULL;
1313 
1314 if (PyODict_CheckExact(od)) {
1315 _odict_FOREACH(od, node) {
>>> CID 1302699: Null pointer dereferences (NULL_RETURNS)
>>> Dereferencing a pointer that might be null "PyDict_GetItem((PyObject *)(PyObject *)od, node->key)" when calling "PyODict_SetItem".
1316 int res = PyODict_SetItem((PyObject *)od_copy,
1317 _odictnode_KEY(node),
1318 _odictnode_VALUE(node, od));
1319 if (res != 0)
1320 goto fail;
1321 }

Correct me if I'm wrong, but this is a duplicate of the bug Stefan reported in issue24347.
