coredump of 9.3.2

Hi!

Rather simple script (original query was a 500 lines of SQL with >100 Mb of 
gzipped dump. Query is looked strange, but actually it was auto-generated):

CREATE TABLE t (a int, b int);
CREATE TABLE tt (c int);

INSERT INTO t VALUES (1,1), (2,2);
INSERT INTO tt VALUES (2);


SELECT    *
FROM    t
WHERE (    CASE        WHEN a%2 IN (SELECT c FROM tt) THEN a    END IN (SELECT c FROM tt)
);

I suppose, the problem is connected to hashed subplan, but I'm not very familiar 
with executor. And this affects all supported versions of pgsql.
