BUG#23080148 - BACKPORT BUG 14653594 AND BUG 20683959 TO
MYSQL-5.5 The bug asks for a backport of bug#1463594 and bug#20682959. This is required because of the fact that if replication is enabled, master transaction can commit whereas slave can't commit due to not exact 'enviroment'. This manifestation is seen in bug#22024200.
