The following script causes an assertion fault on all prior versions of SQLite that support partial indices:

CREATE TABLE t1(a,b);
CREATE UNIQUE INDEX t1ab ON t1(a,b);
CREATE INDEX t1b ON t1(b) WHERE b=1;
INSERT INTO t1(a,b) VALUES(123,456);
UPDATE OR REPLACE t1 SET b=789;

This bug was introduced with the addition of partial index support by check-in [478113f18b1d2860] on 2013-08-02 for SQLite version 3.8.0.
