The binlog contains specially marked format description events to mark when a master restart happened (which could have caused temporary tables to be silently dropped). Such events also cause slave to close temporary tables. However, there was a bug that if after this, slave re-connects to the master in GTID mode, the master can send an old format description event again. If temporary tables are closed when such event is seen for the second time, it might drop temporary tables created after that event, and cause replication failure. With this patch, the restart flag of the format description event is cleared by the master when it is sent to the slave in a subsequent connection, to avoid the errorneous temp table close.
