Description:
------------
array_multisort is chocking when using it's own constants:

EngineException: Cannot pass parameter 4 by reference in Drupal\Core\Extension\ExtensionDiscovery->sort() (line 321 of D:\DRUPAL OFICIAL\drupal\core\lib\Drupal\Core\Extension\ExtensionDiscovery.php).


array_multisort($origins, SORT_ASC, $profiles, SORT_ASC, $all_files);

It get's solved by using variables:

$p = SORT_ASC;
array_multisort($origins, $p, $profiles, $p, $all_files);

Test script:
---------------
<?php

$origins = array();
$profiles = array();
$all_files = array();

array_multisort($origins, SORT_ASC, $profiles, SORT_ASC, $all_files);

I can't reproduce this error. (Ubuntu, current master)

Sorry, looks like the sample script works OK.

But the report (sample line and exception message) is legitimate.

I am unable to build a sample isolated script that triggers the error, but I can't imagine how can any previous code can mess up things to the point where passing SORT_ASC makes array_multisort choke.

The error will be thrown if you add a "namespace Foo;" at the top.

I cannot reproduce either, on windows, just to confirm.
