Please try using this CVS snapshot:

  http://snaps.php.net/php5-STABLE-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php5.0-win32-latest.zip

I ran the code atleast 50 times and it works just fine here.

Description:
------------
[ bad english, i know ]

It seems that PHP 5 is not very stable.
My code segfaults every 3-4 days :'(

Reproduce code:
---------------
<?php

class B {
}

class A {
        public $b;
        public function __construct() {
                $this->b = new B;
        }
        public function build() {
                return $this->b;
        }
}

class C {

        private $b;

        public function __construct() {
                
                $a = new A();
                $this->b = $a->build();
                
                try {
                        throw new Exception;
                } catch(Exception $e) {
                }

        }

        public function __destruct() {
        
                throw new Exception;

        }

}

$C = new C;

?>

Expected result:
----------------
Something like "An uncaught exception has been thrown..."

Note that the code works as expected if you remove the following lines
:

"$a = new A();
$this->b = $a->build();"

Actual result:
--------------
segmentation fault :)
