Programs fail to execute with a runtime error when locale is set.


The following codes fail both for english and greek (haven't checked with other
locales) with the run-time error: 

"terminate called after throwing an instance of 'std::runtime_error'
  what():  locale::facet::_S_create_c_locale name not valid
Aborted".


The codes that fail:


1.

#include <iostream>
#include <locale>
#include <string>


int main()
{
    using namespace std;

    locale::global(locale("en_US"));

    wcin.imbue(locale("greek"));
    wcout.imbue(locale("greek"));

    wstring ws;

    wcin>> ws;

    wcout<< ws<< endl;
} 


2.

#include <iostream>
#include <locale>
#include <string>


int main()
{
    using namespace std;

    ios_base::sync_with_stdio(false);

    wcin.imbue(locale("greek"));
    wcout.imbue(locale("greek"));

    wstring ws;

    wcin>> ws;

    wcout<< ws<< endl;
} 



3.

#include <iostream>
#include <locale>
#include <string>


int main()
{
    using namespace std;



    wcin.imbue(locale("greek"));
    wcout.imbue(locale("greek"));

    wstring ws;

    wcin>> ws;

    wcout<< ws<< endl;
} 



It fails for files too:

4.

#include <locale>
#include <string>
#include <fstream>


int main()
{
    using namespace std;

    wstring ws= L"Test";

    wofstream file("filename.txt");

    file.imbue(locale("greek"));

   if(file.is_open())
      file<< ws;

}


The bug is serious, I can't save unicode texts in my programs!
