### Description

The following code (script provided by @zeriyoshi):

```php
<?php

$foo = [];
$foo[] = new \Exception(); /* Native interface implemented Native instance */
$foo[] = new class () implements \Stringable /* Native interface implemented User instance */
{
    public function __toString(): string
    {
        return "bar";
    }
};

foreach ($foo as $baz) {
    for ($i = 0; $i < 64; $i++) {
        $baz->__toString();
    }
}
```

Resulted in this output:
```
Assertion failed: ((execute_data)->opline) >= ((execute_data)->func)->op_array.opcodes
&& ((execute_data)->opline) < ((execute_data)->func)->op_array.opcodes +
((execute_data)->func)->op_array.last, file
C:\php-sdk\phpdev\vs16\x64\php-src-8.0\ext\opcache\jit/zend_jit_trace.c, line 7679
```

But I expected this output instead:
```
```
