      Description

      Problem reported by nanyi607rao on maria-developers@:

      ...
      else
      {
      if(!(rgi= new rpl_group_info(rli)))

      { my_error(ER_OUTOFMEMORY, MYF(0), (int)sizeof(*rgi)); return NULL; }

      rgi->is_parallel_exec = true;

      • if ((rgi->deferred_events_collecting= rli->mi->rpl_filter->is_on()))
        _ rgi->deferred_events= new Deferred_log_events(rli);
        }
        + if ((rgi->deferred_events_collecting= rli->mi->rpl_filter->is_on()))
        + rgi->deferred_events= new Deferred_log_events(rli);

      because rgi->deferred_events was freed in rpl_parallel_thread::free_rgi() if it wasn't NULL
