Consider the following test case:

CREATE VIRTUAL TABLE vt0 USING fts5(c0, tokenize = "ascii", prefix = 1);
INSERT INTO vt0(c0) VALUES (x'd1');
INSERT INTO vt0(vt0) VALUES('integrity-check'); -- unexpected error: database disk image is malformed

Unexpectedly, the integrity-check fails sometimes/nondeterministically with the error "database disk image is malformed".
