Comment (by anonymous):

 I think what he means is this:

 https://github.com/boostorg/serialization/commit/4f83fc163afad8fc078afcb0eccfbda1f161b3b6


 {{{
  private:
      BOOST_DLLEXPORT static T & instance;
      // include this to provoke instantiation at pre-execution time
 -    static void use(T const &) {}
 +    static void use(T const *) {}
      BOOST_DLLEXPORT static T & get_instance() {
          static detail::singleton_wrapper< T > t;
          // refer to instance, causing it to be instantiated (and
          // initialized at startup on working compilers)
          BOOST_ASSERT(! detail::singleton_wrapper< T >::m_is_destroyed);
 -        use(instance);
 +        use(& instance);
          return static_cast<T &>(t);
      }
  public:
 }}}

 Unfortunately, it didn't fix the problem for me, or rather fixed it, but
 only partially. Now I'm getting another error, along the lines of:
