Consider the following test case:

<pre>
CREATE VIRTUAL TABLE vt0 USING fts5(c0);
INSERT INTO vt0(c0) VALUES (NULL);
BEGIN TRANSACTION;
INSERT INTO vt0(vt0) VALUES('rebuild');
INSERT INTO vt0(vt0) VALUES('rebuild');
INSERT INTO vt0(vt0) VALUES('integrity-check'); -- database disk image is malformed
</pre>

Unexpectedly, the integrity check results in an error "database disk image is malformed".
