Run these queries in debug build:

CREATE TABLE t0 ( c8 INT , CONSTRAINT cc0 UNIQUE i0 ( c8 ) ) ;

INSERT INTO t0 VALUES ( ) , ( ) ;

ALTER TABLE t0 ADD COLUMN c59 TEXT NOT NULL AFTER c8 ;

INSERT INTO t0 VALUES ( -95 , 86 ) , ( -58 , -36 ) ;

SELECT t1 . c41 AS c18 FROM ( SELECT c59 AS c41 FROM t0 ) AS t1 JOIN t0 ON c8 IN ( SELECT c8 AS c45 FROM t0 GROUP BY c59 , c8 HAVING c59 = AVG ( ( SELECT c8 AS c30 FROM t0 HAVING ATAN ( ROUND ( -588949354837696189 , IF ( 6068938522839077129 , -1 BETWEEN 79 AND 49 , 21 ) ) , RAND ( ) ) = t0 . c59 LIMIT 1 ) ) ) ;
