OSC multiple port bug

From CSWiki

OSC bug report, dan trueman

if you try to receive messages on multiple ports, things will eventually crash.

these example scripts will crash fairly quickly when the ports are different, but won't when they are the same.

> chuck send.ck recv.ck

this is reproducible when recv is run on a separate machine, and also when another application is doing the sending and chuck is only receiving.

OSX 10.4.11 MacBook 1/83 GHz recent build from CVS

//send.ck

OscSend xmit1, xmit2;

xmit1.setHost ( "localhost", 6448 ); //if the ports are the same, this won't crash
xmit2.setHost ( "localhost", 6449 );

while (true)
{

	send_msg1(Std.rand2(0, 100));
	Std.rand2(1, 10)::ms => now;
	
	send_msg2(Std.rand2(0, 100));
	Std.rand2(1, 10)::ms => now;

}
	

fun void send_msg1(int outval)
{
		// start the message...

			xmit1.startMsg( "msg1", "i" );

			outval => xmit1.addInt;


}

fun void send_msg2(int outval)
{
		// start the message...

			xmit2.startMsg( "msg2", "i" );

			outval => xmit2.addInt;


}

//recv.ck
spork ~ receive_msg1();
spork ~ receive_msg2();
