      Description

        Sonarcloud reports a possible access to a NULL C++ object in Arena::destruct_contents():

        ```
        _first->chop();
        ```

        I have found no code path where this could happen but _first could conceivably be NULL after a call to Arena::reset(). Lets fix that.
