iterator_adaptor: strange compile error

I get the following error when using a method in one project but not 
the other. I havent got a clue what can be the error.
packages\boost\boost\iterator_adaptors.hpp(628): error C2057: 
expected constant expression
Converter.cpp(83): see reference to template 
instantiation 'boost::iter_adaptor<CollectionIteratorState<iter,Orderb
ookList>,CollectionIter
atorPolicy<OrderbookList>,OrderbookList,OrderbookList&,OrderbookList 
*,random_access_iter_tag,int>' being compiled

In the boost\iterator_adaptors.hpp(638) it states:

   // Iterators >= ForwardIterator must produce real references
    // as required by the C++ standard requirements in Table 74.
    BOOST_STATIC_CONSTANT(bool, forward_iter_with_real_reference =
           (!
boost::is_convertible<iterator_category*,std::forward_iterator_tag*>::
value
           || boost::is_same<reference,value_type&>::value
           || boost::is_same<reference,const value_type&>::value));

And as far I can see at least one of the expressions is true namely
boost::is_same<reference,value_type&>::value should yield 
boost::is_same<OrderbookList&,OrderbookList&>::value wich should be 
true.

I have compared build settings for both projects and the appear to be 
the same. Btw I'm using MSVC 6 latest sp.
