Bug#29915479 RUNNING COM_REGISTER_SLAVE WITHOUT COM_BINLOG_DUMP CAN RESULTS IN SERVER EXIT

Browse Source 
in fact, in MariaDB it cannot, but it can show spurious slaves
in SHOW SLAVE HOSTS.

slave was registered in COM_REGISTER_SLAVE and un-registered after
COM_BINLOG_DUMP. If there was no COM_BINLOG_DUMP, it would never
unregister.
