Bug report

When analysing a file with the following contents, I get a Segmentation Fault (using PHPStan 1.4.4, which didn’t appear on 1.4.3).

Code snippet that reproduces the problem

The demo isn’t able to give me a shareable link as it errors. I tried to reduce the amount of code from this class to isolate the exact issue but removing various methods appears to make the fault go away, so here is the code:

<?php

declare(strict_types=1);

namespace App\Hydrator;

use App\Entity\AttributeOption;
use App\Entity\ProductOption;
use App\Entity\EntityInterface;
use Doctrine\ORM\ORMException;

use function call_user_func;

/**
 * @template T of EntityInterface
 * @template R of AttributeOption|ProductOption
 */
abstract class AbstractWithOptionsHydrator
{
    /** @var string */
    protected const OPTION_OWNER_PROPERTY = '';

    /**
     * @param array<string, mixed> $data
     * @param T $entity
     *
     * @return R
     */
    protected function hydrateOption(array $data, EntityInterface $entity): EntityInterface
    {
        /** @var R $option */
        $option   = $this->optionHydrator->hydrate($data);
        $callable = [$option, 'set' . static::OPTION_OWNER_PROPERTY];
        call_user_func($callable, $entity);

        return $option;
    }
}

Expected output

Show analysis output.
