Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

Reproduced on Windows 2000 when using __sleept() with aggregated objects
as private memembers.
The bug has been reproduced in both PHP 5.2-dev (from link below) and
PHP 5.1.4.

The following script can be used to reproduce the error:
<?php
class TestParent
{
	private $parentPrivateVar;
	protected $parentProtectedVar;
	public $parentPublicVar;
	
	public function __construct($private, $protected, $public)
	{
		$this->parentPrivateVar = $private;
		$this->parentProtectedVar = $protected;
		$this->parentPublicVar = $public;
	}
	
	function __sleep()
	{
		return array("parentPrivateVar", "parentProtectedVar",
"parentPublicVar");
	}
}

class TestChild extends TestParent
{
	private $childPrivateVar;
	protected $childProtectedVar;
	public $childPublicVar;
	
	public function __construct($private, $protected, $public)
	{
		$this->childPrivateVar = "child_". $private;
		$this->childProtectedVar = "child_". $protected;
		$this->childPublicVar = "child_". $public;
		
		parent::__construct("parent_". $private, "parent_". $protected,
"parent_". $public);
	}
	
	function __sleep()
	{
		return array_merge(array("childPrivateVar", "childProtectedVar",
"childPublicVar"), parent::__sleep() );
	}
}

class WebSession
{
	private $privateVar;
	private $privateAggregatedObject;
	
	public function __construct($private, TestChild &$o)
	{
		$this->privateVar = $private;
		$this->privateAggregatedObject = $o;
	}
		
	public function __sleep() { return array("privateVar",
"privateAggregatedObject"); }

	public function getPrivateVar() { return $this->privateVar; }
		
	public function getObject() { return $this->privateAggregatedObject; }
}

// Report simple running errors
error_reporting(E_ERROR | E_PARSE | E_WARNING | E_NOTICE | E_STRICT |
E_USER_ERROR | E_USER_WARNING | E_USER_NOTICE);

// Start user session
session_start();

if(isset($_SESSION['obj_Info']) === false)
{
	$_SESSION['obj_Info'] = new WebSession("private variable", new
TestChild("private", "protected", "public") );
}

echo "<pre>";
var_dump($_SESSION['obj_Info']);
echo "</pre>";
echo "<hr />";
echo "TEST: ". $_SESSION['obj_Info']->getPrivateVar() ."<br
/>";
echo "OBJECT: ". $_SESSION['obj_Info']->getObject() ."<br
/>";
echo "OBJECT PUBLIC VAR: ".
$_SESSION['obj_Info']->getObject()->childPublicVar ."<br />";
?>

GIVES THE FOLLOWING OUTPUT IN PHP 5.1.4:
object(WebSession)#1 (2) {
  ["privateVar:private"]=>
  string(16) "private variable"
  ["privateAggregatedObject:private"]=>
  object(TestChild)#2 (6) {
    ["childPrivateVar:private"]=>
    string(13) "child_private"
    ["childProtectedVar:protected"]=>
    string(15) "child_protected"
    ["childPublicVar"]=>
    string(12) "child_public"
    ["parentPrivateVar:private"]=>
    string(14) "parent_private"
    ["parentProtectedVar:protected"]=>
    string(16) "parent_protected"
    ["parentPublicVar"]=>
    string(13) "parent_public"
  }
}

TEST: private variable
OBJECT: Object id #2
OBJECT PUBLIC VAR: child_public

Notice: Unknown: "parentPrivateVar" returned as member variable from
__sleep() but does not exist in Unknown on line 0

The notice is only thrown on the initial run with "parentPrivateVar" is
actually set.
The notice is not thrown if "parentPrivateVar" is null.

In PHP 5.2-dev the scrip dies line 76: echo "OBJECT: ".
$_SESSION['obj_Info']->getObject() ."<br />";
The notice is still thrown when "parentPrivateVar" is set though.
