          CREATE TABLE t1 (i1 INT, c1 VARCHAR(6)) ENGINE=MyISAM;
INSERT INTO t1 VALUES (1,'foo'),(2,'bar');

CREATE TABLE t2 (c2 VARCHAR(6)) ENGINE=MyISAM;
INSERT INTO t2 VALUES ('foobar'),('qux');

CREATE ALGORITHM=MERGE VIEW v1 AS SELECT * FROM t1 WHERE ( c1, c1 ) IN ( SELECT c2, c2 FROM t2 ) AND i1 <= 2 ;

PREPARE stmt FROM 'SELECT * FROM t1 LEFT JOIN v1 ON (v1.i1 = t1.i1)';

EXECUTE stmt;
EXECUTE stmt;

          Also reproducible with a subquery instead of the view (in this case derived_merge=on is required).
