The following SQL gives an assertion fault while running the SELECT in the CREATE TABLE statement:
CREATE TABLE t1(a TEXT); INSERT INTO t1(a) VALUES(1),(2); CREATE TABLE t2(x TEXT, y TEXT); INSERT INTO t2(x,y) VALUES(3,4); CREATE TEMP TABLE t3 AS SELECT a AS p, coalesce(y,a) AS q FROM t1 LEFT JOIN t2 ON a=x;
This problem was reported on the firstname.lastname@example.org mailing list by Nissl Reinhard. Bisecting shows that the problem was introduced by check-in [36b613ccf0ddb764a].

This appears to be the same underlying problem as ticket [43107840f1c02], just in a different spot in the code.
