On PHP 5.6 [debug tests are failing](https://travis-ci.org/symfony/symfony/jobs/29118115#L357) with:

```
PHP Fatal error:  Class 'Psr\Log\LogLevel' not found in /home/travis/build/symfony/symfony/src/Symfony/Component/Debug/ErrorHandler.php on line 522
```

I think https://github.com/symfony/Debug/commit/4bd5484d456e6263acc6429fabea7e2fbc74fffc#diff-b91ca53d6ab50b804cb5783aaf1f9740R71 introduced the problem. Alternative fix would be to initialize the `$loggers` in a constructor.

The syntax check functionality has been removed in PHPUnit 3.6 already. But there's no Composer constraint for PHPUnit, so you can never know which version will actually be used to run tests. Let me know what you think.
