I try to run this. I find it compile well.but when I run it., it core dump.

Although the D spec says you can pass a string for a "%.*s" format, it 
really only works on 32-bit targets.  The argument for '*' is of type 
'int', not 'size_t'. On a 64-bit target, passing a char[] really passes 
a 'size_t' and 'char*', which is not what printf expects.

To be portable, you have to do this:

	string s2 = ss.readline();
	printf("%.*s\n", cast(int) s2.length, s2.ptr);

Sorry, I mean socket.connect can't work  in freebsd 8/amd64.

    ........
    writefln("Befor");
    sock.connect(new InternetAddress("www.digitalmars.com", 80));
    writefln("After");
I test this ,it just output "Befor" and then core dump.
