I'm surprised that that program even compiles.  What version of boost are
you using and what compiler.  Does this program work better?

#include <string>
#include <iostream>

#include<boost/filesystem/convenience.hpp>
namespace bf = boost::filesystem;

int main() {
    std::string name("/calvin/hobbes/xx.xml");
    bf::path filepath(name);
    std::cerr << "Value for basename: " <<
        basename(filepath) << std::endl;
}
