Undefined variable $result in Container.php

Laravel Version

PHP Version

8.5.0

Database Driver & Version

MySQL 8.0.42

Description

When running php artisan schedule:run, an ErrorException: Undefined variable $result is thrown in Container.php.
The error occurs in the following code path:

if ($this->resolved($abstract)) {
    $this->rebound($abstract);
}

return $result;  // <-- $result is undefined

It appears that $result is being returned without being defined in certain code paths within the Container class.

Steps To Reproduce

Run php artisan schedule:run (the exact trigger may vary)
The error is thrown from Illuminate\Container\Container.php

Stack Trace:
ErrorException: Undefined variable $result

vendor/laravel/framework/src/Illuminate/Container/Container.php
  in Illuminate\Foundation\Bootstrap\HandleExceptions::handleError
Environment

Expected Behavior
The container method should properly initialize and return $result in all code paths without throwing an undefined variable error.
Additional Context
This error was captured in production via error monitoring. The breadcrumbs show:

artisan.command → Finished artisan command: schedule:run
The error triggers during the command execution lifecycle

$result is clearly defined in line 799:

framework/src/Illuminate/Container/Container.php

Lines 799 to 805 in e4551e7

	$result = BoundMethod::call($this, $callback, $parameters, $defaultMethod);
	if ($pushedToBuildStack) {
	array_pop($this->buildStack);
	}
	return $result;

I know it is defined, but we are still getting this error from production environment.

Horizon deprecated warning might cause this error:

Method ReflectionProperty::setAccessible() is deprecated since 8.5, as it has no effect in /var/www/html/vendor/laravel/horizon/src/Tags.php on line 121

For now I can only provide error logs below:

I believe this Horizon PR will fix this problem: laravel/horizon#1676

This PR doesn't solve the problem FYI.

How can we reproduce the issue on a fresh installation?

[frkcn]

We resolved this issue by disabling OPcache JIT. Adding the following configuration fixed the problem:

opcache.jit = off
opcache.jit_buffer_size = 0

This appears to be related to JIT compilation causing unexpected behavior with PHP 8.5.

Hope this helps anyone encountering the same issue!
