I don't get the crash any more with the change you applied a little
while ago.  Here's a test case that was crashing:

CREATE TABLE foo (
    id          serial PRIMARY KEY,
    first_date  date NOT NULL,
    last_date   date NOT NULL
);

CREATE INDEX foo_dates_idx ON foo (first_date, last_date);

INSERT INTO foo (first_date, last_date) VALUES ('2005-04-01', '2005-04-02');
INSERT INTO foo (first_date, last_date) VALUES ('2005-04-02', '2005-04-03');
INSERT INTO foo (first_date, last_date) VALUES ('2005-04-03', '2005-04-04');
INSERT INTO foo (first_date, last_date) VALUES ('2005-04-04', '2005-04-05');

ANALYZE foo;

SELECT * FROM foo WHERE first_date <= now() AND last_date >= now();
 id | first_date | last_date
----+------------+------------
  1 | 2005-04-01 | 2005-04-02
(1 row)

And now back to the "date - range" thread in pgsql-performance,
which is why I was looking at this in the first place....
