Major Description
Run these queries in debug build:
CREATE TABLE x ( x INT ) ;
INSERT INTO x ( x ) VALUES ( 1 ) ;
UPDATE x SET x = 1 IN ( WITH RECURSIVE x ( x ) AS ( WITH x ( x ) AS ( SELECT 1 EXCEPT SELECT x + 1 FROM x WHERE x = 1 AND ( x = 1 OR x = 1 OR x = 1 ) WINDOW x AS ( ORDER BY x ) , x AS ( ORDER BY x ) ) SELECT 1 UNION SELECT x FROM x WHERE x IN ( 1 , 1 , 1 ) ) SELECT 1 ) WHERE x = 1 ;
Will trigger use-after-poison.
