>Description:
When a slave is pointing to a non-existing master, doing "slave start/slave
stop"
will sometimes cause the MySQL server to crash
>How-To-Repeat:
mysql> change master to master_host='bogus', master_log_file='';
Query OK, 0 rows affected (0.00 sec)
mysql> slave start;
ERROR 2006: MySQL server has gone away
No connection. Trying to reconnect...
Connection id: 2
Current database: *** NONE ***
ERROR 1198: This operation cannot be performed with a running slave, run SLAVE STOP
first
The server doesn't always crash. When I type "slave start/slave stop", I maybe see a
crash 10% of the time.
