Symfony功能测试在升级到2.2之后会产生无限循环

我在Symfony从2.1升级到2.2后遇到了问题。当一次运行所有功能测试时(注意，当运行单个测试时不会发生这种情况，无论哪个)，我得到一个错误，无限循环卡在

PHP Fatal error:  Maximum function nesting level of '150' reached, aborting! in project_path'vendor'symfony'symfony'src'Symfony'Component'ClassLoader'DebugClassLoader.php on line 81

在我升级之前，所有的测试都工作得很好，现在他们在使用

$form = $crawler->selectButton('Login')->form();
$form['_password'] = '123ASDasd';
$form['_username'] = 'MattKing';
$crawler = $client->submit($form); //this is LoginControllerTest.php:53 from error above

或

$link = $crawler->selectLink('Matt King')->link();
$client->click($link); // --> error

或

$client = static::createClient();
$client->followRedirects(true);
$crawler = $client->request('GET', '/login'); // --> error

另一个问题是在使用默认symfony翻译函数时。切换用户的语言环境后，测试抛出了与上面相同的错误。当我注释掉切换语言环境时，就会出现其他错误(如上面的错误)。请注意，它可能是由与上面相同的问题引起的。

我已经找了几天原因，放弃了。知道怎么解决这个问题吗?
