Private property in base class

[rlalak]

When I serialize object which extends some base class with private property after unserialize I have default value for this property and extra field (with the same name) in not base class.

Classes

class TestBase
{
 private $name = 'default';

 public function getName()
{
 return $this->name;
 }

 public function setName($name)
{
 $this->name = $name;
 }
}

class Test extends TestBase
{

}

Code

$test = new Test();

$test->setName('new-name');
var_dump($test, $test->getName());

$new_test = msgpack_unpack(msgpack_pack($test));
var_dump($new_test, $new_test->getName());

Output

object(Test)#579 (1){
 ["name":"TestBase":private]=>
 string(8) "new-name"
}
string(8) "new-name"


object(Test)#588 (2){
 ["name":"TestBase":private]=>
 string(7) "default"
 ["name"]=>
 string(8) "new-name"
}
string(7) "default"

As you see method getName() return incorrect value in new object.
