The bug happened because filtering-out a STMT_END_F-flagged event so that
the transaction COMMIT finds traces of incomplete statement commit.
Such situation is only possible with ndb circular replication. The filtered-out
rows event is one that immediately preceeds the COMMIT query event.
      
Fixed with deploying an the rows-log-event statement commit at executing
of the transaction COMMIT event. 
Resources that were allocated by other than STMT_END_F-flagged event of
the last statement are clean up prior execution of the commit logics.
