Comment 1 for bug 1355722

Yes, there's a rather low chance to get inconsistent binary log coordinates when backing up 5.1 servers. Note that data consistency is not affected.

Using FLUSH LOGS instead of FLUSH ENGINE LOGS looks too invasive for a backup utility.

Closing this report as invalid, but thank you for catching this regexp bug in detect_mysql_capabilities_for_backup()! Reported separately as bug #1357404.
