## 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
.scanstats off
PRAGMA full_column_names = NO;
PRAGMA encoding;
PRAGMA fullsync = YES;
.stats
CREATE TABLE "v"(b, d, e);
CREATE TABLE u(a, b, c);
ANALYZE sqlite_master;
INSERT INTO "sqlite_stat1" VALUES('u','uab','40000 400 1');
INSERT INTO "sqlite_stat1" VALUES('v','vbde','40000 400 1 1');
INSERT INTO "sqlite_stat1" VALUES('v','ve','40000 21');
CREATE INDEX uab on u(a, b);
CREATE INDEX ve on v(e);
CREATE INDEX vbde on v(b,d,e);
DROP TABLE IF EXISTS sqlite_stat4;
ANALYZE sqlite_master;

ALTER TABLE u ADD COLUMN extra_8479 DATETIME DEFAULT (random());
REINDEX v;
SELECT * FROM u WHERE b = (SELECT GROUP_CONCAT(b) FROM u);
DELETE FROM v WHERE rowid = 60 RETURNING *;
```
