there is an error with the


static const char *const _Future_messages[] = { // messages for future errors "broken promise", "future already retrieved", "promise already satisfied", "no state" };


this code generated an invalid acceso to "_Future_messages" because _Mycode.value() return 4.

const char *__CLR_OR_THIS_CALL what() const _THROW0() { // get message string return (_Get_future_error_what(_Mycode.value())); }

// code example

   std::future<int> empty;
   try {
       int n = empty.get();
   } catch (const std::future_error& e) {
      const error_code eCode = e.code();
      char *sValue = (char*)e.what();
      std::cout << "Caught a future_error with code " << eCode.message()
                 << " - what" << sValue << endl;
   }
works for me, and for the online compilers (even http://ideone.com/bkXoAM ). Perhaps you need to direct this query to Microsoft Connect? --Cubbi (talk) 03:37, 16 October 2013 (PDT)
