### Description
The following code:
```php
<?php
abstract class LinkedList { }
final class Cons extends LinkedList
{
public function __construct(
public mixed $head,
public LinkedList $tail
) { }
}
final class Nil extends LinkedList { }
$list = new Nil();
for ($i = 0; $i < 100000; $i++) {
$list = new Cons(random_int(0, PHP_INT_MAX), $list);
}
```
Resulted in this output:
```
Process finished with exit code 139 (interrupted by signal 11: SIGSEGV)
```
But I expected this output instead:
```
Process finished with exit code 0
```
