      Description

      Mariadb crash, daily, consistently, after upgrade from 10.5.7 to 10.5.8. Simple database, just a lot of InnoDB tables and a few MyISAM tables. No stored procedures.

      This is seen consistently at least once a day. The mariadb server crashes, gets restarted. The backtrace is consistent too about json_locate_key, fill_variables... etc.
