## 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 full_column_names = YES;
PRAGMA soft_heap_limit = 10000000;
PRAGMA checkpoint_fullsync = OFF;
.auth ON
CREATE TABLE t3(x,y);
INSERT INTO t3 VALUES(1,NULL);
INSERT INTO t3 VALUES(2,NULL);
INSERT INTO t3 VALUES(3,4);
SELECT count(x), y FROM t3 GROUP BY y ORDER BY 1;
PRAGMA recursive_triggers;
UPDATE t3 SET x = 'x' WHERE x IS NOT NULL RETURNING *;
WITH cte AS (SELECT * FROM t3 WHERE x IS NOT NULL) SELECT * FROM cte;
ANALYZE;
REINDEX;
INSERT INTO t3 VALUES (NULL, NULL);
CREATE TRIGGER IF NOT EXISTS trg_t3_8438 AFTER INSERT ON t3 FOR EACH ROW BEGIN INSERT INTO t3(y) VALUES (NULL); END;

SELECT a,b,c,
