Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read
http://bugs.php.net/bugs-generating-backtrace.php for *NIX and
http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32

Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.

I can't reproduce any problem with this test script.

Description:
------------
I am not good at english.. 



Read the following code ..



An error occurs when you run it..

(there will be white-screen in my codes.)







Chinese :

如果你能看懂中文.那最好不过了.
上面的代码我认为__destruct被继承之后,
会导致下面两个类的对象在释放时出现无法找到static
$childs的错误.
但是在我的代码里面他确实没有出现这个错误,
反而运行了很久之后出现了白屏.
看上去很像一个死循环.



Test script:
---------------
error_reporting(E_ALL);

ini_set('display_errors', 'on');



abstract class Father {

   private static $childs = array();



   public static function getChild( $child ) {

       if (!array_key_exists("$child", self::$childs)) {

           self::$childs["$child"] = new $child;

       }

       return self::$childs["$child"];

   }



   public function __destruct() {

       foreach (self::$childs as $i => $child) {

            self::$childs[$i] = $child = null;

       }

   }

}



class Child1 extends Father {}

class Child2 extends Father {}



$child1 = Father::getChild('Child1');

$child2 = Father::getChild('Child2');
