System: Linux kiste 2.4.17 #7 Thu Jan 3 17:21:51 CET 2002 i686 unknown
Architecture: i686
SuSE 7.3
glibc 2.2.4 + patches
host: i686-pc-linux-gnu

>Description:
There are new problems with named locales. When I take the test case
included in PR/libstdc++ 5280 and set LANG=fr_FR, the program does not
run normally. It comsumes all virtual memory until it is killed by
the kernel, a killed message appears. If I remember correctly the
program worked when I last tried about a week ago.  

>How-To-Repeat:
source code tl.C

#include <iostream>
#include <locale>
#include <string>
#include <cstdlib>
using namespace std;

int main()
{
  locale coutLocale("");
  cout.imbue(coutLocale);
  string s;
  cin >> s;
  if (!cin) {
    cerr << "ERROR while reading the locale" << endl;
    return EXIT_FAILURE;
  }
  

  locale cinLocale(s.c_str());
  cin.imbue(cinLocale);

  cout << "cout locale: " << coutLocale.name() << endl;
  cout << "cin locale: " << cinLocale.name() << endl;
  double value;
  while (cin >> value) {
    cout << value << endl;
  }
  cout<<"rdstate after reading from cin : "
      << cin.rdstate() << endl;
  cout<<"good eof fail bad "
      << ios::goodbit << " "
      << ios::eofbit << " "
      << ios::failbit << " "
      << ios::badbit << endl;

}
