## 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
BEGIN IMMEDIATE TRANSACTION;
.limit
CREATE TABLE T1 (
a INTEGER,
b TEXT
);
CREATE TABLE T2 (
a INTEGER,
b TEXT
);
INSERT INTO T1 VALUES (1,'a'),(2,'b');
INSERT INTO T2 VALUES (1,'c'),(1,'d');
SELECT T1.b,
(
SELECT GROUP_CONCAT(b,',')
FROM T2
WHERE T2.a=T1.a
) AS c
FROM T1;
ROLLBACK;
```
## Actual output
```sql
length 1000000000
sql_length 1000000000
column 2000
expr_depth 1000
compound_select 500
vdbe_op 250000000
function_arg 127
attached 10
like_pattern_length 50000
variable_number 32766
trigger_depth 1000
worker_threads 0
a|c,d
b|
```
## Expectation
```sql
length 1000000000

compound_select 500
vdbe_op 250000000
