Should just be catch(std::exception &e)

}
cout << "nonexistant:is_file = " << path("nonexistant").is_file() << endl;

Same thing here catch(std::exception &e).

{
cout << "<file does not exist>" << endl;
}
cout << "filesystem/path.h:exists = " << path("filesystem/path.h").exists() << endl;
cout << "filesystem/path.h:is_file = " << path("filesystem/path.h").is_file() << endl;
cout << "filesystem/path.h:is_directory = " << path("filesystem/path.h").is_directory() << endl;

this part of the try block actually gets executed
output looks like you would expect:

nonexistant:file_size = <file does not exist>

}
cout << "../filesystem:is_file = " << path("../filesystem").is_file() << endl;
cout << "../filesystem:is_directory = " << path("../filesystem").is_directory() << endl;
cout << "../filesystem:extension = " << path("../filesystem").extension() << endl;
