      Description

      Hi,

      I am upgrading from MySQL 5.6.14 to MariaDB 10.0.18 and ran into a bug. After upgrading the mysql_upgrade script upgrades all the views, enabling the general query log showed me the last query is executed when upgrading the second view (upgrading the first view succeeds but upgrading the second view crashes the thread):

      REPAIR NO_WRITE_TO_BINLOG VIEW `click_url_view` FROM MYSQL;
      ERROR 2013 (HY000): Lost connection to MySQL server during query
      MariaDB [db]> REPAIR NO_WRITE_TO_BINLOG VIEW `click_url_view` FROM MYSQL;
      ERROR 2006 (HY000): MySQL server has gone away
      No connection. Trying to reconnect...
      Connection id:    5
      Current database: db

      The view definition (according to MySQL 5.6):

      root@localhost [db] > show create view click_url_view\G
      *************************** 1. row ***************************
                      View: click_url_view
               Create View: CREATE ALGORITHM=UNDEFINED DEFINER=`root`@`localhost` SQL SECURITY DEFINER VIEW `click_url_view` AS select `AP`.`ad_id` AS `ad_id`,`A`.`click_url` AS `click_url`,greatest(`A`.`created`,`AP`.`created`) AS `created`,greatest(`A`.`modified`,`AP`.`modified`) AS `modified` from (`ad_part` `AP` join `asset` `A` on((`AP`.`ad_part_id` = `A`.`ad_part_id`))) where ((`A`.`click_url` is not null) and (`A`.`asset_type` = 'promoted_video') and (`AP`.`status` = 'Active') and (`A`.`status` = 'Active')) group by `AP`.`ad_id`
      character_set_client: utf8
      collation_connection: utf8_unicode_ci
      1 row in set (0.00 sec)

      The view definition according to MariaDB seams to be the same:

      MariaDB [db]> show create view click_url_view\G
      *************************** 1. row ***************************
                      View: click_url_view
               Create View: CREATE ALGORITHM=UNDEFINED DEFINER=`root`@`localhost` SQL SECURITY DEFINER VIEW `click_url_view` AS select `AP`.`ad_id` AS `ad_id`,`A`.`click_url` AS `click_url`,greatest(`A`.`created`,`AP`.`created`) AS `created`,greatest(`A`.`modified`,`AP`.`modified`) AS `modified` from (`ad_part` `AP` join `asset` `A` on((`AP`.`ad_part_id` = `A`.`ad_part_id`))) where ((`A`.`click_url` is not null) and (`A`.`asset_type` = 'promoted_video') and (`AP`.`status` = 'Active') and (`A`.`status` = 'Active')) group by `AP`.`ad_id`
      character_set_client: utf8
      collation_connection: utf8_unicode_ci

      The view .frm file on MySQL 5.6:

      The view .frm file on MariaDB (after trying to run REPAIR VIEW):
