Bug#747103: libc6-dev: setlocale in static binary fails

[Raphael <raphael.astier@eliot-sa.com>]

Package: libc6-dev
Version: 2.13-38
Severity: important

Hello list,

I'm trying to use setlocale() in a static binary, and I compil with:

$ gcc -Wall -static code.c -o code

When I run 
$ ./code 

I expect to see "lundi" instead of "Monday", but it's not working with static compilation.
(it's ok in dynamic compil. with: $gcc -Wall -code.c -o code).

The locale "fr_FR" is correctly installed on my system (package locales configured with fr_FR).

The code.c is fairly simple : 

#include <stdio.h>
#include <locale.h> 
#include <langinfo.h> 
int main(void)
{
setlocale (LC_ALL, "fr_FR");
printf("%s\n",nl_langinfo(DAY_2));
return 0;
}

I have done some debug (with gcc -ggdb) : 

- the return of setlocale is correct "fr_FR" in static and dyn. compil, 
- it seems to me that setdata()/setname() in file setlocale.c don't do right job (pb with CATEGORY_USED(category))
- I have try use of: 
  $ cd tmp ; localedef -i fr_FR -f ISO-8859-1 ./fr_FR
  and put in code.c before setlocale():
  setenv("LOCPATH","/home/raphael/tmp,1);
  but: it's not better in static compilation
- I have noticed with $strace -eopen ./code 
  that in dynamic compil : open("/home/raphael/tmp/fr_FR/LC_xxx", O_RDONLY) = 3 (with setenv)
                           open("/usr/lib/locale/locale-archive", O_RDONLY|O_LARGEFILE) = 3  (without setenv)
  but in static compil with setenv and setlocale(LC_TIME, "fr_FR"); nothing is opened ...

I have tried this code under different OS : 
  
- RedHat Enterprise Linux Server release 5.5 (Tikanga) or 6  --> it works as expected
- Debian Etch, Debian Lenny --> it works as expected
- Debian Wheezy --> the bug is present  

Thank you
