fwiw for me even the first line fails.
i don't know how c++ locales are supposed to work.

$ cat
#include <locale>
using namespace std;
int main()
    return 0;

$ g++
$ ./a.out 
terminate called after throwing an instance of 'std::runtime_error'
  what():  locale::facet::_S_create_c_locale name not valid
