If no GTIDs have been generated the binlog reader will fail to start with a message error in initializing slave: basic_string::erase in the logs.

mysql> show master status\G
*************************** 1. row ***************************
             File: mysql-bin.000007
         Position: 154
     Binlog_Do_DB: 
 Binlog_Ignore_DB: 
Executed_Gtid_Set:

Once a GTID has been generated the binary will start as expected. Either the binlog reader should handle this condition or the error message should be made clearer.

Fix initialization when 'Executed_Gtid_Set' is empty sysown#7
09087e9 
If 'Executed_Gtid_Set' is found empty and invalid query is sent towards
the server, and an infinite loop can take place once 'get_remote_binlog'
is called. We prevent this by waiting until the first 'GTID' has been
processed.
