I had tried this before.  It also throws.
It would have to be:

    int processFile(const fs::path& fileName)
    {
        fs::path copyFileName(fileName.string() + ".bak", fs::native);
        fs::copy_file(fileName, copyFileName);
    }

I'd probably write it like this, just for stylistic reasons:

    int processFile(const fs::path& fileName)
    {
        fs::copy_file(fileName,
                fs::path(fileName.string() + ".bak", fs::native));

    }

Also, if you haven't already done something similar, change the name of 
your main() function to cpp_main, after adding:

    #include <boost/test/included/prg_exec_monitor.hpp>

That will turn the exceptions into something more readable.
