## 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
.progress 9999
PRAGMA cell_size_check = NO;
ATTACH DATABASE ':memory:' AS aux65;
CREATE TABLE T (
a VARCHAR(255),
b CHARACTER(20),
c INTEGER
);
INSERT INTO T VALUES (NULL,'a',NULL), (2,'b',1), (3,'c',2);
WITH RECURSIVE d(a,b,c,e) AS (
SELECT *,1 FROM T WHERE c IS NULL
UNION ALL
SELECT T.a,T.b,T.c,d.e+1
FROM T JOIN d ON T.c=d.a
)
SELECT * FROM d;
.timer on
CREATE TABLE T1 (
A VARCHAR(-1445937777629738465),
X VARCHAR(10),
PRIMARY KEY (A, X),

INSERT INTO T1 VALUES ('a', 'm');
