 Description   

Run these queries in debug build:

CREATE TABLE t0 ( c18 DOUBLE ( 219 , 15 ) ) ;
INSERT INTO t0 VALUES ( 8381074827123138459 ) , ( 1 ) ;
CREATE INDEX i0 ON t0 ( c18 ) ;
INSERT INTO t0 VALUES ( -13 ) , ( 116 ) ;
SELECT CASE -108 WHEN RAND ( ) = LOCATE ( t1 . c17 , 'J(W{$vSaYbyeLs)7cRzT2r<e' , LTRIM ( t1 . c17 ) ) THEN 95 ELSE FIND_IN_SET ( -126 , '74"#;6q5o,r
7Ty$35lq"_BY*zA:QhWoOcv.1%0' ) END AS c20 FROM ( SELECT TRIM( TRAILING FROM t0 . c18 ) AS c17 FROM t0 ) AS t1 JOIN t0 ON t1 . c17 = t0 . c18 ;

Will trigger Heap-Use-After-Free.
