Description

Note: There is ~~MDEV-22380~~ about the assertion failure mentioned below, but the situation seems to be different here. First, the failures described here started happening recently (see details below); and secondly, the test cases from ~~MDEV-22380~~ don't seem to cause ASAN errors, while the one in this report does.

CREATE TABLE t (f INT);

INSERT INTO t VALUES (1),(2);

CREATE VIEW v1 AS SELECT * FROM t WHERE f IS NULL;

CREATE VIEW v2 AS SELECT * FROM v1 UNION SELECT * FROM t;

PREPARE stmt FROM "SELECT * FROM v2 WHERE f <= 1 OR f > 9";

SET optimizer_trace= 'enabled=on';

EXECUTE stmt;

EXECUTE stmt;

# Cleanup

DROP VIEW v2;

DROP VIEW v1;

DROP TABLE t;

Reproducible on 10.4+ with at least MyISAM and InnoDB.
The test case is not applicable to earlier versions due to the use of optimizer trace, and I wasn't able to convert the test case below into a non-optimizer-trace variation the same way as ~~MDEV-22380~~ suggests. However, the failure started happening in 10.4 after the merge below, so it's possible that the root cause is also present in earlier versions.
