      Testcase (fails on second execution of prepare statement):

      CREATE TABLE t1 (
        col1 int(8),
        col2 int(10)
      ) ENGINE=MyISAM;
       
      CREATE VIEW v1 AS SELECT col2, (SELECT col1 FROM t1 HAVING col2=1) FROM (SELECT * FROM t1) as a;
      explain SELECT * FROM v1;
       
      prepare stmt from "SELECT * FROM v1";
      execute stmt;
      execute stmt;
      deallocate prepare stmt;
       
      drop view v1;
      drop table t1;
