Description

I have two queries that return some data from information_schema about table structures and foreign keys (sql.txt).
But once per 5-6 executions mariadb-server crashed and goes to restart.
Same logs are appear in journalctl (log.txt).
Executing CALL `forms_data_columns`('', 'U') cause crash each even times.
