Memory leak on running query in PS mode with condition that has 'ANY/SOME (subquery)' clause and any kind of the following comparisons '>', '>=', '<', '<=' '

CREATE TABLE t1 (s1 CHAR(1));

INSERT INTO t1 VALUES ('a');

SELECT * FROM t1 WHERE _utf8'a' > ANY (SELECT s1 FROM t1);

DROP TABLE t1;

CREATE TABLE t1 (f1 CHAR(3) CHARACTER SET utf8 NULL, f2 CHAR(3) CHARACTER SET latin1 NULL);

INSERT INTO t1 VALUES ('foo','bar');

SELECT * FROM t1 WHERE f2 >= SOME ( SELECT f1 FROM t1 );

DROP TABLE t1;
