## 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
.stats
CREATE TABLE t1(a, b TEXT);
CREATE UNIQUE INDEX IF NOT EXISTS x1 ON t1(b==0);
CREATE INDEX IF NOT EXISTS x2 ON t1(a || 0) WHERE b;
INSERT INTO t1(a,b) VALUES('a',1),('a',0);
SELECT a, b, '|' FROM t1;

DROP INDEX IF EXISTS t1;
```

## Actual output

```sql

Number of Outstanding Allocations:   0 (max 2)
Number of Pcache Overflow Bytes:     0 (max 0) bytes
Largest Allocation:                  40 bytes
Largest Pcache Allocation:           0 bytes
Bytes received by read():            6545
Bytes sent to write():               0
