        Fix for MDEV-5531: double call procedure in one session - hard shutdown the server
        Main fix was to not cache derivied tables as they may be temporary tables that are deleted before the next query.
        This was a bit tricky as Item_field::fix_fields depended on cached_tables to be set to resolve some columns.

      CREATE TABLE t1 (a INT, b INT) ENGINE=MyISAM;
      CREATE TABLE t2 (c INT) ENGINE=MyISAM;
      INSERT INTO t1 VALUES (1,1),(2,2);
      INSERT INTO t2 VALUES (3),(4);
       
      PREPARE stmt FROM 'SELECT * FROM ( SELECT DISTINCT * FROM t1 ) AS sq WHERE a IN ( SELECT c FROM t2 WHERE c <= sq.b )';
      EXECUTE stmt;
      EXECUTE stmt;

      query 'EXECUTE stmt' failed: 1054: Unknown column 'sq.b' in 'where clause'
