在所有的版本中都表现正常。。你的描述有点不清楚。这段代码本来就不会有什么输出。
我先关闭了，如果有问题你再reopen吧。

I can't reproduce it, seems not a but,
Closed for now, if you have any issues, please reopen it.

I'm unable to reproduce any error's or a white screen.
Code looks fine, although it is a bit of a strange construction.

Recommend closing this bug as "not a bug" as it has been open for 1,5 years now.

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');
