If replication breaks in GTID mode, it is not trivial to determine the GTID of the failing event group. This is a problem, as such GTID is needed eg. to explicitly set @@gtid_slave_pos to skip to after that event group, or to compare errors on different servers, etc. Fix by ensuring that relevant slave errors logged to the error log include the GTID of the event group containing the problem event.
