I have found what I think is a problem with
basic_text_iprimitive/wiprimitive. When linking a windows clr dll (may
happen with other configurations too), if you use both serialization and
wserialization you should not be able to link because of a couple of
symbols defined across two different modules (is_whitespace(char) and
is_whitespace(wchar_t) in basic_text_iprimitive and basic_text_wiprimitive).

I solved the problem by changing this two files and rebuilding boost:

// basic_text_iprimitive.ipp:

    template<>
    bool is_whitespace(char t);
//    {
//        return 0 != std::isspace(t);
//    }

    #ifndef BOOST_NO_CWCHAR
    template<>
    bool is_whitespace(wchar_t t);
//    {
//        return 0 != std::iswspace(t);
//    }
    #endif
} // detail

// basic_text_iprimitive.cpp:

namespace detail {
    template<class CharType>
    bool is_whitespace(CharType c);

    template<>
    bool is_whitespace(char t)
    {
        return 0 != std::isspace(t);
    }

    #ifndef BOOST_NO_CWCHAR
    template<>
    bool is_whitespace(wchar_t t)
    {
        return 0 != std::iswspace(t);
    }
    #endif
} // detail

Regards.
