      Description

      If server is started with --skip-innodb (without skipping InnoDB information_schema plugins), the information schema tables are still there. Normally attempts to select from them produce a reasonable warning:

      MariaDB [test]> select * from INFORMATION_SCHEMA.INNODB_SYS_TABLESTATS;
      Empty set, 1 warning (0.00 sec)
       
      MariaDB [test]> show warnings;
      +---------+------+----------------------------------------------------------------------------------------------------------------+
      | Level   | Code | Message                                                                                                        |
      +---------+------+----------------------------------------------------------------------------------------------------------------+
      | Warning | 1012 | InnoDB: SELECTing from INFORMATION_SCHEMA.INNODB_SYS_TABLESTATS but the InnoDB storage engine is not installed |
      +---------+------+----------------------------------------------------------------------------------------------------------------+
      1 row in set (0.00 sec)
      

      But selecting from INFORMATION_SCHEMA.INNODB_TEMP_TABLE_INFO causes a crash:

      MariaDB [test]> SELECT * FROM INFORMATION_SCHEMA.INNODB_TEMP_TABLE_INFO;
      ERROR 2013 (HY000): Lost connection to MySQL server during query
