Sorry, I cannot test latest snapshot on FreeBSD system, I try it on WinXP with following results:

Test 1:

<?
    $obj = new stdClass();
    $obj->prop1 = '1';
    $obj->prop2 = '2';


    $reflect = new ReflectionObject($obj);
    $array = array();
    foreach($reflect->getProperties() as $prop)
    {
        $array[$prop->getName()] = $prop->getValue($obj);
    }

    print_r($array);
?>

Expected result:

Array
(
    [prop1] => 1
    [prop2] => 2
)

Actual result: 

Array
(
    [prop1] => 2
    [prop2] => 
)

Test 2:

<?
    $obj = new stdClass();
    $obj->prop1 = '1';
    $obj->prop2 = '2';
    $obj->prop3 = '3';



    $reflect = new ReflectionObject($obj);
    $array = array();
    foreach($reflect->getProperties() as $prop)
    {
        $array[$prop->getName()] = $prop->getValue($obj);
    }

    print_r($array);
?>

Expected result:

Array
(
    [prop1] => 1
    [prop2] => 2
    [prop3] => 3
)

Actual result: 

Fatal error: Cannot access property started with '\0' in C:\php\test.php on line 12

Still does not work property.
