FPM exit code 70 with enabled opcache and hooked properties in traits

[zenas1210]

Description

Preloading a class:

<?php

require_once __DIR__ . '/DummyTrait.php';

class DummyModel
{
    use DummyTrait;
}

that uses a trait which has hooked properties:

<?php

trait DummyTrait
{
    public ?string $dummyProperty1 = null; // This doesn't crash

    public ?string $dummyProperty2 { // This crashes
        get => null;
    }
}

into opcache makes FPM fail to start with code 70, in other cases throws segmentation fault. Reproducer app: https://github.com/zenas1210/bug-reproducer.

Seems to affect all 8.4.* versions.
