When binglog_format is "row", DML statements would have a Table_map_event in binlog; each Table_map_event would have a table_id; the table_id is represented as ulong in binlog, while read into TABLE_LIST.table_id in slave, which is of type uint, so if table_id is larger than 2^32, it would cause type overflow, and those events in relay log would be silently skipped, hence causing data inconsistency between master and slave.
