Description

Run these queries in debug build:

CREATE TABLE x ( x INT ) ;

INSERT INTO x ( x ) VALUES ( 1 ) ;

UPDATE x SET x = 1 WHERE x = 1 ;

INSERT INTO x ( x ) VALUES ( 1 ) , ( 1 ) ;

WITH x ( x ) AS ( SELECT 1 EXCEPT SELECT x + 1 FROM x ) SELECT x - x , x + x FROM x WHERE x IS NULL AND x IS NULL GROUP BY x HAVING ( SELECT CASE WHEN x = 1 THEN 1 ELSE x + 1 END , x FROM x GROUP BY x + 1 , 1 NOT IN ( SELECT 1.000000 ^ 1.000000 FROM x WHERE 'x' * ( x LIKE 'x' ) > 'x' * 1 + x GROUP BY x ) ) NOT IN ( SELECT x , x FROM x GROUP BY 1 HAVING 1.000000 + 1.000000 ) ORDER BY x DESC LIMIT 1 ;

Will trigger heap-use-after-free:
