10641,boost::filesystem::path::parent_path() throws run time error locale::facet::_S_create_c_locale name not valid,maxiaoyin@…,Beman Dawes,"I have the following code under ubuntu 12.04 with gcc 4.3.6 .

{{{
#include <iostream>
#include <boost/filesystem/path.hpp>
using namespace std;
namespace fs = boost::filesystem
int main(int argc, char** argv)
{

	try
	{
		fs::path my_path(""test/test.txt"");
		cout << ""current path is      "" << my_path << endl;
		cout << ""parent path is       "" << my_path.parent_path() << endl;
	}
	catch(std::exception& e) {
		cerr << endl << ""Error during execution: "" << e.what() << endl << endl;
		return EXIT_FAILURE;
	}
	return EXIT_SUCCESS;
}
}}}

I was able to create a path using the string ""test/test.txt"" and print out the path as a string. However, when I was trying to access the parent_path() or stem() or extension()  the program will fail and throw locale::facet::_S_create_c_locale name not valid error.

output: 
current path is      ""test/test.txt""

Error during execution: locale::facet::_S_create_c_locale name not valid
