Snippet to crash PHP7.

Without the unset, $var isn't changed and returns same content as before.
If array is empty in the first assignment you get a notice that $var is an uninitialized var.

<?php
    $configuration = array(
        'controllerConfiguration' => array(
            'TheFirstController' => array(
            ),
        )
    );
    $var = current(array_keys($configuration['controllerConfiguration']));
    var_dump($var);

    unset($configuration['controllerConfiguration']['TheFirstController']);

    $configuration['controllerConfiguration'] = array();
    $var = current(array_keys($configuration['controllerConfiguration']));
    var_dump($var);

Dragged this down a bit further.

The crash happens on following line:
https://github.com/TYPO3/TYPO3.CMS/blob/master/typo3/sysext/extbase/Classes/Mvc/Web/RequestBuilder.php#L110

$this->defaultControllerName =
current(array_keys($configuration['controllerConfiguration']));

in the crashing test, this is an empty array. But trying this in a 10 lines test doesn't fail.

I run it normaly with

phpunit -c typo3/sysext/core/Build/UnitTests.xml

At the moment I use PHPUnit 4.6.6
