Consider the following statements:

CREATE VIRTUAL TABLE vt0 USING fts4(c0, languageid="lid");
INSERT INTO vt0 VALUES (0), (1);
UPDATE vt0 SET lid = 1;
INSERT INTO vt0(vt0) VALUES('integrity-check'); -- unexpected: database disk image is malformed

Unexpectedly, the integrity check results in an error "database disk image is malformed". Without the BEGIN, the check executes without error.
