    Hello,

    There is probably some bug in computing # frames in nbest list. The # frames
    in n-best lists is much greater than the actual # frames. This seems to be
    happening whenever the search couldn't end in

    Below is the trace in the log file. Here actual # frames in 43, but in the
    nbest file this is pronted as 136
