I can change the assert to:

      assert(m->_data_size + m->_extra_data_size == rec->_data_length * (int)sizeof(rec->_data[0]) ||
             m->_data_size == rec->_data_length * (int)sizeof(rec->_data[0]), "must agree”);

and then it covers both cases. There’s no real need to detect whether the replay file has extra data.

Roland.
