### Description
The following code leaks memory when observed:
```php
<?php
$closure = function() { /* observe this */ };
$object = new class {};
$mem = memory_get_usage();
while (true) {
if ($mem != memory_get_usage()) {
var_dump($mem = memory_get_usage());
}
$closure->call($object);
}
```
To reproduce, run with
php -dzend_test.observer.enabled=1 -dzend_test.observer.observe_all=1
-dzend_test.observer.show_output=0 and see memory consumption explode.
