[issue21938] Py_XDECREF statement in gen_iternext()

[Xavier de Gaye]

New submission from Xavier de Gaye:

The Py_XDECREF statement in gen_iternext() at Objects/genobject.c is not needed since val is NULL (may be optimized out by the compiler).
Actually, the whole function could be written as:

    return gen_send_ex(gen, NULL, 0);
