 Description   

The following script crashes the server. We encountered this on 10.2.16 and I have also tested this on 10.2.17 and its the the same. We think the problem is the EXISTS() element.

DROP TABLE IF EXISTS TEST_TABLE_1;
CREATE TABLE TEST_TABLE_1 (
UID BIGINT
);

DROP TABLE IF EXISTS TEST_TABLE_2;
CREATE TABLE TEST_TABLE_2 (
UID BIGINT
);

DROP TABLE IF EXISTS TEST_TABLE_3;
CREATE TABLE TEST_TABLE_3 (
UID BIGINT
);

SELECT
ROW_NUMBER() OVER (PARTITION BY GROUP_CONCAT(TT1.UID))
FROM TEST_TABLE_1 TT1
WHERE EXISTS (
SELECT *
FROM TEST_TABLE_2 TT2
JOIN TEST_TABLE_3 TT3 ON TT2.UID = TT3.UID
WHERE TT3.UID = TT1.UID
)
GROUP BY TT1.UID
;

Thanks for the report!
It looks like it is the same bug as MDEV-15178, on debug version it fails
with assertion `pos->field != __null || pos->item != __null' in Filesort::make_sortorder:
