## Summary
<!--Explain briefly what goes wrong and explain why you believe this is a bug and not the intended behavior of SQLite (if it is not a crash).-->**No review yet**

## Minimized query

```sql
CREATE TABLE one(o);
INSERT INTO one DEFAULT VALUES;
CREATE TABLE t1(x, z);
INSERT INTO t1 VALUES('aaa', unicode(NULL));
INSERT INTO t1 VALUES('aaa', unicode('A'));
CREATE VIEW vvv AS SELECT * FROM t1 UNION ALL SELECT typeof(NULL), unhex(0, ' ') WHERE 0;
SELECT /**/ ( SELECT sum(z) FROM vvv WHERE x='aaa' ) FROM one;

CREATE  VIEW IF NOT EXISTS v_t1_7523 AS SELECT x FROM t1;

SELECT COUNT(*) FROM one;
CREATE TEMPORARY  VIEW IF NOT EXISTS v_one_9622 AS SELECT o FROM one;
SELECT * FROM one WHERE o IN (SELECT o FROM one WHERE o IN (SELECT o FROM one));
ALTER TABLE t1 RENAME COLUMN z TO z_r2864;
ALTER TABLE one RENAME COLUMN o TO o_r5469;
INSERT OR ABORT INTO one VALUES ('');
ALTER TABLE t1 ADD COLUMN extra_5466 FLOA DEFAULT 0;
