Unfortunately it is very hard for me to help since I 
don't have your environment.  Perhaps you can put some
I/O traces in to see if we can isolate where it is crashing.
Perhaps you annotate boost/date_time/date_formatting.hpp
~ line 69 in ymd_formatter, method ymd_to_string.  Here's
what you are looking for.  I've added a few cout's to 
gather data:

    static std::string ymd_to_string(ymd_type ymd)
    {
      typedef typename ymd_type::month_type month_type;
      std::ostringstream ss;
      ss << ymd.year;
      std::cout << "year ok" << std::endl;
      if (format_type::has_date_sep_chars()) {
        ss << format_type::month_sep_char();
      }
      //this name is a bit ugly, oh well....
      month_formatter<month_type,format_type>::format_month(ymd.month, ss);
      std::cout << "month format ok" << std::endl;
      if (format_type::has_date_sep_chars()) {
        ss << format_type::day_sep_char();
      }
      std::cout << "month ok" << std::endl;

      ss  << std::setw(2) << std::setfill('0') 
          << ymd.day;
      std::cout << "day ok" << std::endl;

      return ss.str();
    }

Also, this shouldn't matter, but try changing your test 
to remove the leading '0' from the month:

>    std::cout << to_simple_string( date( 2003,6,12) )
>       << std::endl;

Thx,
