 It seems that this function

 {{{
 template<typename int_type_>
 class int_adapter {

   static int_adapter from_special(special_values sv)
   {
     switch (sv) {
     case not_a_date_time: return not_a_number();
     case neg_infin:       return neg_infinity();
     case pos_infin:       return pos_infinity();
     case max_date_time:   return (max)();
     case min_date_time:   return (min)();
     default:              return not_a_number();
     }
   }

 }}}

 is not been inlined with gcc 3.4.6 and so it is duplicated at link time.
 See link error on regression test
