Problem with the fr_FR locale and libstdc++ with GCC 4.3.2

["David Ritter" <David.Ritter@xxxxxxxxxxxxx>]

Hello,

I am seeing what I believe is a bug with GCC 4.3.2 and libstdc++ and I
wanted to know if anyone else has seen it.

With the following code, if I run it on GCC 4.3.2 there is no weekday
number returned by the time_get() call.  However if I run the same code
on GCC 3.4.6 or GCC 4.1.2 it runs correctly.

Is this a known issue?

/********* Test case *******/
#include <sstream>
#include <locale>
#include <iostream>
#include <assert.h>

int main()
{
    const char* name = "fr_FR";
    const char* fmt = "%A";
    std::string str;
    struct tm t = tm();
    std::locale loc (name);

    t.tm_wday  = 2;

    {
      typedef std::ostreambuf_iterator<char> iter_t;

      std::ostringstream os;
      os.imbue (loc);
      iter_t os_iter(os.rdbuf ());

      const char* fmt_end = fmt + std::char_traits<char>::length(fmt);

      const std::time_put<char,iter_t>& fac =
            std::use_facet<std::time_put<char,iter_t> >(loc);

      fac.put(os_iter, os, os.fill(), &t, fmt, fmt_end);

      str = os.str();

      std::cout << "From the ostream" << std::endl
              << str << std::endl;

    }

    t.tm_wday  = 0;

    {
      typedef std::istreambuf_iterator<char> iter_t;

      std::istringstream is(str);
      iter_t start(is);
      iter_t end;
      is.imbue(loc);

      const std::time_get<char,iter_t>& fac =
            std::use_facet<std::time_get<char,iter_t> >(loc);

      std::ios_base::iostate err (std::ios_base::goodbit);          

      fac.get_weekday(start, end, is, err, &t);

      if (err == std::ios_base::failbit || err == std::ios_base::badbit)
{
        fprintf(stdout, "error\n");
      }

      fprintf(stdout, "Reflected number is %d\n", t.tm_wday); 
    }

    return 0;
}
/****** End Test ******/

// expected output (from GCC 3.4.6 & GCC 4.1.2)
>From the ostream
mardi
Reflected number is 2

// Error output from (GCC 4.3.2)
>From the ostream
mardi
error
Reflected number is 0



Thanks you for any help,
