Description:
------------
This PHP code generates a segmentation fault.

I would expect an error message such as :
Fatal error: Declaration of B::c() must be compatible with A::c() in /tmp/test.php on line 13


Test script:
---------------
<?php
abstract class A {
	
	abstract public function c();
	
}

class B extends A {
	
	public function c(...$list) {
	}
	
}
?>

Expected result:
----------------
A nice error message:

Fatal error: Declaration of B::c() must be compatible with A::c() in /tmp/test.php on line 13

Actual result:
--------------
A segmentation fault:

vincent@abricow:/var/www$ php /tmp/test.php 
Erreur de segmentation (core dumped)
