Version 3.0.3 breaks Symfony PHP Dependency Injection

[entepe85]

After updating zend-code to version 3.0.3 through composer update the following error is thrown upon clearing the Symfony cache:

Fatal error: Uncaught Symfony\Component\Debug\Exception\FatalThrowableError: Parse error: syntax error, unexpected '\' (T_NS_SEPARATOR), expecting identifier (T_STRING) in [...]var/cache/dev/appDevDebugProjectContainer.php:7161

Here's the corresponding line of code:
class VichUploaderBundleHandlerUploadHandler_000000003557d388000000006581de10da75941a549785cf26d7df71050c90e4 extends \\Vich\UploaderBundle\Handler\UploadHandler implements \\ProxyManager\Proxy\VirtualProxyInterface {

Reverting zend-code back to 3.0.2 through composer.json fixes the above issue.

You can try this in your composer.json while waiting for the fix to be released (hopefully in 3.0.4)
"zendframework/zend-code": "~3.0.2, !=3.0.3"
