Description
It might be related to MDEV-21245, which is about the same assertion failure, but otherwise different stack trace. Other numerous JIRA reports about this assertion failure are closed at this moment.

CREATE TABLE t1 (a VARCHAR(8)) ENGINE=InnoDB; |
INSERT INTO t1 VALUES ('foo'),('bar'); |
|
|
CREATE TABLE t2 (b VARCHAR(256), KEY(b)) ENGINE=InnoDB; |
INSERT INTO t2 VALUES ('1'),('2'),('3'),('4'),('5'),('6'),('7'),('8'),('9'),('10'); |
SET SQL_MODE= ''; |
ALTER TABLE t2 MODIFY b VARCHAR(3073); |
|
|
SELECT * FROM t1 JOIN t2 FORCE INDEX(b) ON a = b; |
|
|
# Cleanup
|
DROP TABLE t1, t2; |
Note: Originally the problem was observed without FORCE INDEX, but then it required innodb_stats_persistent (which is default in the server, but not in MTR) and, on some reason, table encryption. FORCE INDEX allowed to get rid of both.

Reproducible on 10.2-10.5.
Non-debug build doesn't crash, but the warnings InnoDB: Using a partial-field key prefix in search are still there.
