When creating the cache, a syntax error is still present since the issue #9807. The #9812 fix does not solve the problem. ##### Error: ``` PHP Parse error: syntax error, unexpected '\' (T_NS_SEPARATOR), expecting identifier (T_STRING) in ./app/cache/dev/appDevDebugPr ojectContainer.php ``` In my case, the line: ``` php $g = \Doctrine\\ORM\\EntityManager::create($this->get('doctrine.dbal.default_connection'), $f); ``` should be formatted like this: ``` php $g = \Doctrine\ORM\EntityManager::create($this->get('doctrine.dbal.default_connection'), $f); ```
