Description

How to repeat:
First, initialize an empty database by the file `init_by_me.txt`.
Second, run the following statement:

UPDATE IGNORE t49 SET c1 = 'h' WHERE (NULL LIKE c1) IS NOT TRUE;

I got the following trace

I got a simplified test case as follows.

CREATE TABLE t0 (c1 CHAR, c2 NUMERIC UNSIGNED, PRIMARY KEY (c1, c2));

CREATE TABLE t1 (c2 CHARACTER, FOREIGN KEY (c2) REFERENCES t0(c1) MATCH FULL ON UPDATE CASCADE);

INSERT INTO t0 (c1,c2) VALUES ('',0), ('h',0), ('',21);

CREATE FULLTEXT INDEX i1 ON t1(c2 DESC);

CREATE INDEX i2 ON t1(c2 ASC) ALGORITHM = COPY;

INSERT INTO t1 (c2) VALUES ('');

UPDATE IGNORE t0 SET c1 = 'h' WHERE (NULL LIKE c1) IS NOT TRUE; -- Crash

Shortest case to repeat the issue:

--source include/have_innodb.inc

CREATE TABLE t1 (c1 CHAR NOT NULL, c2 INT UNSIGNED,

                 PRIMARY KEY (c1, c2))ENGINE=InnoDB;

CREATE TABLE t2 (c1 INT UNSIGNED, c2 CHAR NOT NULL, INDEX(c2),

                 FOREIGN KEY (c2) REFERENCES t1(c1) ON UPDATE CASCADE)

                ENGINE=InnoDB;

INSERT IGNORE INTO t1 (c1,c2) VALUES

        (null, 0), (null, 1), ('h', 0);

ALTER TABLE t2 ADD FULLTEXT(c2);

INSERT IGNORE INTO t2 (c1,c2) VALUES (5617,null);

UPDATE IGNORE t1 SET c1 = 'h';

DROP TABLE t2, t1;
