## 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
PRAGMA query_only = 0;
PRAGMA encoding = 'UTF-16be';
PRAGMA auto_vacuum = NONE;
.timer on
CREATE TABLE t1(a,b INT);
INSERT INTO t1(a,b) VALUES(1,2),(3,3),(4,5);
CREATE UNIQUE INDEX i1 ON t1(b,b,a,a,a,a,a,b,a);
ANALYZE;
DROP TABLE IF EXISTS sqlite_stat4;
INSERT INTO sqlite_stat1 VALUES('t1','i1','30 30 30 2 2 2 2 2 2 2');
ANALYZE sqlite_master;

PRAGMA checkpoint_fullsync = NO;
```

## Actual output

```sql
Run Time: real 0.000 user 0.000094 sys 0.000000
Run Time: real 0.000 user 0.000019 sys 0.000000

Run Time: real 0.000 user 0.000003 sys 0.000000
```
