    Description

      delete_returning test fails in MDEV-8646 tree.

      Crashing queries:

      CREATE TABLE t1 (i1 int);
      		 
      INSERT INTO t1 VALUES (1),(2);
      		 
      CREATE TABLE t2 (i2 int);
      		 
      INSERT INTO t2 VALUES (1),(2);
      		 
      DELETE FROM t1 ORDER BY i1 RETURNING ( SELECT i2 FROM t2 );

      The reason the last one crashes is that the execution code first calls:

      JOIN::cleanup (this=0x7fff64065c68, full=true)

      and then it calls

      JOIN::exec (this=0x7fff64065c68)

      that is, attempts to execute a join where it already did a cleanup.

            The "exec-after-cleanup" can be observed on MariaDB 10.0, too. It doesn't crash, because in 10.0, a join can survive JOIN::exec() after JOIN::cleanup(full=true).
