Query_log_event::error_code A query can perform completely having the local var error of mysql_$query zero, where $query in insert, update, delete, load, and be binlogged with error_code e.g KILLED_QUERY while there is no reason do to so. That can happen because Query_log_event consults thd->killed flag to evaluate error_code. Fixed with implementing a scheme suggested and partly implemented at time of bug@22725 work-on. error_status is cached immediatly after the control leaves the main rows-loop and that instance always corresponds to `error' the local of mysql_$query functions. The cached value is passed to Query_log_event constructor, not the default thd->killed which can be changed in between of the caching and the constructing.
