Bug description: Always tries to connect to client on same outgoing port
Description:
------------
I am connecting to myself and then closing, to sniff out available ports
on my system that I can use-- I'm sure you're acquainted with this
method.
It should always produce a different port (nPort), since no connection is
erected (because it's UDP), but it always returns that it is on the SAME
port.

Reproduce code:
---------------
$n = 10;
while($n--)
{
$strIP = $nPort = -1;
$Socket = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP);
socket_connect($Socket, '172.0.0.1', 8400);
socket_getsockname($Socket, $strAddr, $nPort);
socket_close($Socket);
print("> Available port: $strAddr:$nPort\n");
}
Expected result:
----------------
It produces ten lines of output, that should each contain one unique,
available port number.
Actual result:
--------------
Each line indicates the same port, even if a socket has been opened for
listening on it.
The problem I am having, therefore, is that I sniff the next available
port from this code, and set up a listener on it. I then do the same thing
again in order to open another listener on a different port, but it always
returns to me the same port number, and I can not not bind it, obviously.
Is this intended?
