[Bug c++/15467] New: std::locale("") throws exception

[bryan at reigndropsfall dot net]

running the attached test case throws an exception when my environment variable
LC_ALL is set to anything other than "C" or "POSIX".  This should not be the
case.  std::locale() should accept the same names as setlocale().

This is a bug in glibc.
As libstdc++ just calls:
    __cloc = __newlocale(1 << LC_ALL, __s, __old);

Is glibc supposed to throw C++-style exceptions at all? I'd like to 
hear from the libstdc++ maintainers about this issue.

Note I asked the person to file a glibc bug, see <http://sources.redhat.com/bugzilla/show_bug.cgi?
id=165>, the reason why I said this is not a libstdc++ bug as glibc returns NULL which causes 
libstdc++ to throw the exception.  I should have said that in the bug when I had marked it as invalid.

Probably, the issue is simpler: for some reason, submitter doesn't have
installed any localedata.

Are you on a glibc platform? Could you please provide the output of
'localedef --list-archive' ??

In general, are those named locales otherwise available? I.e., what happens
if you compile and run a simple C test program like the below (in the named
locale of your choice, of course):

#define _GNU_SOURCE 1
#include <locale.h>
#include <langinfo.h>
#include <stdio.h>
#include <time.h>

int main()
{
  locale_t    loc;

  const char* pp;
  const char*   __s = "fr_FR";
 
  loc = newlocale(1 << LC_ALL, __s, 0);

  pp = nl_langinfo_l(ABDAY_1, loc);
  printf("ABDAY_1 = %s\n", pp);

  freelocale(loc);

  return 0;
}

???

... or perhaps the glibc is too old and the thread-local locale support is
missing/broken (that would be the case if the named locales are actually
available only via setlocale). Is your glibc at least 2.2.5, better 2.3.x?

Not a bug in either glibc or libstdc++, see the glibc bug
<http://sources.redhat.com/bugzilla/show_bug.cgi?id=165>, it works if you have the locales installed.
