Bug description:zend_class_unserialize_deny does not work

Description:
------------
Disabling unserialize() for a class does not work when object_common1 is
hit

In pecl/hidef trunk right now FrozenArray is marked with
zend_class_unserialize_deny 

+    ce.serialize = zend_class_serialize_deny;
+    ce.unserialize = zend_class_unserialize_deny;

http://svn.php.net/viewvc/pecl/hidef/trunk/frozenarray.c?r1=311588&r2=313761

But the following code still fails to throw an exception (with hidef
installed)

I traced the code to 

#0  frozen_array_new (ce=0xe34790) at
/home/gopalv/apc_debug/hidef54/frozenarray.c:185
#1  0x00000000006a035b in _object_and_properties_init (arg=0x7ffff7fc8a38,

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

$s='O:11:"FrozenArray":3:{i:1;s:3:"xyz";i:2;s:3:"abc";i:0;s:5:"hello";}'; 

$a = unserialize($s);

print_r($a);


Expected result:
----------------
Fatal error: Uncaught exception 'Exception' with message 'Unserialization
of 'FrozenArray' is not allowed' 


Actual result:
--------------
FrozenArray Object
