Description:
------------
When the code I've supplied is executed, PHP crashes, leaving a segfault message in Apache's log.

The code looks a little perverse, though a variation on it had a real use in my situation, but regardless, PHP shouldn't segfault, no matter how perverse the code is :)

Reproduce code:
---------------
class MC {
	public $Vars = array();
	public function Execute() {
		if (!defined('DONE')) {
			define('DONE', true);
			foreach ($this->Vars as $k => $v) { $$k = $v; }
			$MyArr['Var'] = $MyArr;
			$MC = new MC();
			$MC->Vars = $MyArr;
			$MC->Execute();
		}
	}
}
$MyArr = array();
$MyArr['Var'] = $MyArr;
$MC = new MC();
$MC->Vars = $MyArr;
$MC->Execute();
echo "Hello world.";

Expected result:
----------------
"Hello world." should be printed.

Actual result:
--------------
Nothing is printed, and a segfault line is added to /var/log/apache2/error.log:
