Description

Update: see the new test case in the comment.

The test case is highly non-deterministic, run with --repeat=N. Depending on the build type, it fails for me within 10-50 attempts, but it can vary a lot on different machines and builds.

--source include/have_innodb.inc

CREATE TABLE t1 (a INT, KEY(a)) ENGINE=InnoDB;

CREATE TABLE t2 (b INT) ENGINE=InnoDB;

CREATE  VIEW v2 AS SELECT * FROM t2;

--connect (con1,localhost,root,,test)

ALTER TABLE t2 ADD FOREIGN KEY(b) REFERENCES t1 (a) ON UPDATE CASCADE;

--send

  UPDATE t1, v2 SET t1.a = 1;

--connection default

DROP TABLE IF EXISTS x;

FLUSH TABLES;

--connection con1

--reap

--disconnect con1

--connection default

DROP VIEW v2;

DROP TABLE t2, t1;

All of debug, non-debug and ASAN builds fail, but it takes longer on non-debug.
Couldn't reproduce with the provided test case on 10.4, maybe it's just the matter of luck or different dynamics, or maybe the problem really doesn't exist there.
