    Description

      ATTN: The failure is observed on bb-10.6-monty 9654bf9dd904, not on a main branch!

      The attached data directory was created using MySQL 5.7.42 release and partitioning examples from MySQL manual. The server was shut down normally afterwards.

      MariaDB starts on the datadir with usual complains about mysql.event and alike, but crashes while executing mysql_upgrade, specifically when it runs this query:

      SELECT DISTINCT LOWER(engine) AS c1 FROM information_schema.tables WHERE table_comment LIKE 'Unknown storage engine%' ORDER BY c1

      The same outcome can be achieved by running the query directly on the newly started server.
