Description:
------------
Hello PHP-Community,

i have very strange behaviour with object.

My setup is: 

Ubuntu 10.04 LTS (8vCPU, 12GB RAM)
nginx/0.7.65 
PHP-FPM 5.3.3-1ubuntu9.3ppa1~lucid1 (https://launchpad.net/~fabianarias/+archive/php5)

The server works great at all for a while, and then some of the 20 Processes seemed not to work correctly. The test script keeps failing until i restart the php5-fpm processes. 

It is 100% an PHP error. Our research on the problem gives us the clue that writing on internal variables in objects is working (dump of $this), but the reading of that is not.

This is really strange, and if there is a better possibility to get more debug information on php, please advise me.

P.S. This error also occures on an apache+PHP 5.3.2-1ubuntu4.7 with only one process!





Test script:
---------------
<?

class testme{
        protected $protected;
        public $public;

        public function __construct(){
                $this->protected = 'WORKS!';
                $this->public = 'WORKS!';

                echo '<br>TEST protected: '.$this->protected.'<br>';
                echo '<br>TEST public: '.$this->public.'<br>';
                
                var_dump($this);

                phpinfo();

        }
}

new testme();


Expected result:
----------------
TEST protected: WORKS!

TEST public: WORKS!
object(testme)#1 (2) { ["protected":protected]=> string(6) "WORKS!" ["public"]=> string(6) "WORKS!" } 


Actual result:
--------------
TEST protected:

TEST public:
object(testme)#1 (2) { ["protected":protected]=> string(6) "WORKS!" ["public"]=> string(6) "WORKS!" }
