Comment

[ Thank you for the bug report. Best reduced/optimized testcase thus far:
{code:sql}
CREATE TABLE t (c INT) ENGINE=InnoDB;
SELECT * FROM (SELECT 1 FROM t AS a,t) AS b JOIN t AS d NATURAL JOIN t WINDOW e AS (PARTITION BY c AND 1 BETWEEN (SELECT c FROM t GROUP BY c WINDOW f AS (PARTITION BY c)) AND 2);
{code}

Leads to:
