Code snippet that reproduces the problem

File from error:

<?php

/**
 * This file was automatically generated by generate:mutationEndpoints
 */

declare(strict_types=1);

namespace Slant\Normalizer\Endpoints\Generated;

use Firehed\API\Interfaces\HandlesOwnErrorsInterface;
use Slant\Normalizer\Attributes\ContextInterface;
use Slant\Normalizer\Endpoints\AuthenticatedEndpointInterface;
use Slant\Normalizer\Endpoints\Traits\GeneratedMutationEndpoint;

class GeneratedMutationRemoveAliasFromConnectedNode implements
    AuthenticatedEndpointInterface,
    HandlesOwnErrorsInterface
{
    use GeneratedMutationEndpoint {
        __construct as traitConstructor;
    }

    public function __construct(ContextInterface $context)
    {
        $this->traitConstructor($context, new \Slant\Normalizer\Mutations\RemoveAliasFromConnectedNode());
    }

    // Not done by provided mutation because this is used in a static
    // context (and the definition hasn't been updated)
    public function getUri(): string
    {
        return '/mutations/remove_alias_from_connected_node$';
    }
}

I can provide the trait in question if it's relevant, but my guess is the problem is around the aliased trait method import.

Expected output

No error/no crash. This analyzes and runs fine in 8.0.

This bug report is missing a link to reproduction on phpstan.org.

It will most likely be closed after manual review.

Hi, I need a small reproducing repository to understand what's going on.

[edubacco]

Hi, as I found the same bug, I've created a small repo useful to reproduce it:
https://github.com/edubacco/phpstan-bug-5954-php81

[Firehed]

Thanks @edubacco - I was having trouble boiling down my original issue into a reproduce case, glad you were able to find one!

hi all. I have laravel 8, php8.1 rc5.
i see this error too. If necessary, I will give the code. Nothing is ordinary there. Plain OOP, inheritance and traits
It debug ouput:

This is definitely PHP 8.1 bug (can you reproduce that on PHP 8.0 or not?), it's a matter of isolating that to a small piece of PHP code and reporting that to https://bugs.php.net/.

[1thew]

The phpstun problem appeared only after switching to php 8.1
And this problem repeats itself in completely different code. I have php81 on 4 projects - each problem

[1thew]

But I'm not surprised.
I had to include a reboot mechanism in FPM. Because the php-children-processes began to fall.

I wasn't able to reproduce this with a simple PHP script, but the crashing code in question is supposed to fix a different PHP bug that should no longer happen on PHP 8.0+, so I just wrote an if statement around it: phpstan/phpstan-src@6573959

Please test PHPStan's dev-master to see if it fixes your problem.

if I'm off in class "use FilterTrait" - phpstan works great!
I found a function that is causing problems. Code simplified. It laravel 8

<?php

namespace App\Repositories;

use App\Repositories\ValueObjects\Sort;
use Illuminate\Database\Eloquent\Builder;

trait TestTrait
{
    protected function createResponseDto(
        Builder|\Illuminate\Database\Query\Builder $builder,
        ?Sort $sort
    ): void {
        $builder
            ->when(null !== $sort, function (
                Builder|\Illuminate\Database\Query\Builder $query
            ) use ($sort) {
                return $query->orderBy($sort->getField(), $sort->getMethod());
            });
    }
}

Any inclusion of a trait in any class - breaks phpstan
