Some days ago, I tried a script containing a syntax error and executed it on both Symfony's server wrapper (executed using server:run command) and Nginx/PHP-FPM.

Using Nginx I had the syntax error as expected but using the Symfony's wrapper I had a segfault, crashing the web server.

I precise that only the server:run command is returning a segfault. The server:start command run as expected.

Test script:

namespace AppBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;

class DefaultController extends Controller
    public function indexAction()
        $response = $this->render('')

Expected result:
Parse error: syntax error, unexpected '}' 

Actual result:
[OK] Server running on                                                                           

 // Quit the server with CONTROL-C.
  RUN  '/usr/bin/php7.0' '-S' '' '/home/booteille/PhpstormProjects/my_project/vendor/symfony/symfony/src/Symfony/Bundle/FrameworkBundle/Resources/config/router_dev.php'
