Suggestion:

#define PyStringObject_SIZE (offsetof(PyStringObject, ob_sval) + 1)


        /* Inline PyObject_NewVar */
-       op = (PyStringObject *)PyObject_MALLOC(sizeof(PyStringObject) + size);
        /* Inline PyObject_NewVar */
+       op = (PyStringObject *)PyObject_MALLOC(PyStringObject_SIZE + size);
