FPM exit code 70 with enabled opcache and hooked properties in traits #18534
Description
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.
