Sorry, no, because of this another static object:

   const std::codecvt<wchar_t, char, std::mbstate_t> *
          converter(
             &std::use_facet<std::codecvt<wchar_t, char, std::mbstate_t> >
              ( loc() ) );

which cals 'loc' before 'main' is called, and gives the same problem.

I don't know because I don't know the what() text of the exception thrown on
wrong locale. As soon as we get *some* exception caught, things will be
clearer.
