Summary: crash deserializing 1.32 data (poly archive + stl container)

Initial Comment:
Hello,

i got a problem deserializing STL containers with
polymorphic archive interfaces.

Serialization/Deserialization with boost 1.32 works fine.
Simple object trees with stl containers (maps) and base
class registration (no shared_ptr used).

When i deserialize the data (xml) with boost 1.33 it
asserts/crashes in basic_iarchive.cpp (
basic_iarchive_impl::reset_object_address):

--- snip ----

inline void 
basic_iarchive_impl::reset_object_address(
    const void * new_address, 
    const void *old_address
){
    // if the this object wasn't tracked
    std::size_t i = moveable_object_position;
    if(i >= moveable_object_stack.size())
        return;
    if(old_address != object_id_vector[i].address)
        // skip to any lower level ones
        ++i;
    while(i < moveable_object_stack.size()){
        // calculate displacement from this level
        assert(object_id_vector[i].address >=
old_address); <---- assert here !!!
        // warning - pointer arithmetic on void * is in
herently non-portable
        // but expected to work on all platforms in
current usage
        std::size_t member_displacement
            =
reinterpret_cast<std::size_t>(object_id_vector[i].address) 
            - reinterpret_cast<std::size_t>(old_address);

----
The serializing code is implemented using split members
and manual registration and usually read like this:
---- snip  ---
void DerivedLayoutObject::serialize(
boost::archive::polymorphic_oarchive& ar, const
unsigned int /* version */)
{
	// register pointer type info
	ar.register_type(static_cast<LayoutObject*>(0));
	// serialize data members
	ar & boost::serialization::make_nvp( "status", m_status);
       ....
	// serialize stl  container (std::map here)
	ar & boost::serialization::make_nvp( "childs", m_childs);
}
(deserialization vise-versa)
---------------------
Whats the problem here?
I simply rebuilt the whole project using 1.33.
