Bug description:  Lost object variables during execution of a 
register_shutdown_function

I'm running php4.2.3 on apache/1.3.24(w2k) as a module.

This are my two classes: (Explanations see below)

<?

class A {
        
        function init() {
                register_shutdown_function(array(&$this, 'flush'));     
        }
        
        function flush() {
                if(sizeof($this->logs) > 0) {
                        /* Write it to a file */
                }
        }
}

class B extends A {

        function B($file) {
                $this->file = $file;
                $this->init();
        }
        
        function log($msg) {
                $this->logs[] = $msg;
        }
}

$d = new B('/path/to/logs/debugger.messages');

$d->log('text one');
$d->log('text ten');

?>

I would like to call the flush()-method on shutdown that the logs could be
written to file. So I register it in the init()-method with
register_shutdown_function(array(&$this, 'flush')) and the init()-method
is called from the constructor of class B.

I expected that the $this->logs array would be available and I could write
it to a file.

But the variable was always empty and the sizeof() returns 0. Do I call
the flush()-method manually at the end of the script, everything works
like expected. Every variable set in the constructor B(), like
$this->file, is available in the flush()-method called by the registered
shutdown function. Every variable set later does not exist.

Is that a bug? or just misscoding...
