Py_XDECREF(ptr); ptr = NULL;
But other unsafe idiomatic code is widely used in the sources: Py_XDECREF(ptr); ptr = new_value;Every occurrence of such code is potential bug for same reasons as for Py_CLEAR. It was offered [1] to introduce new macros Py_REPLACE and Py_XREPLACE for safe replace with Py_DECREF and Py_XDECREF respectively. Automatically generated patch contains about 50 replaces [2].
