This is reproducible and not limited to the vm I specified.  I also  
ran this with vm: 'Squeak 3.8.12beta4U.app' and it crashed.  Also, it  
crashes almost immediately, unlike what I said earlier.  Also, there  
are several problems.  The crash is described below.  I am also  
getting code simulation errors using MessageTally tallySends:  
[...].   I think this sets up the crash.

I dug into the code and this is what I found.  This code crashes the vm:

	Socket new connectTo: 1 port: 80.

I call #connectTo:port: with an argument of 1 due to interference by  
the MessageTally.  When I run the code below I crash:

	| addr s |
	Socket initializeNetwork.
	MessageTally tallySends: [
		addr := NetNameResolver addressForName: 'www.google.org'.
		(s := SafeSocket new) connectTo: addr port: 80.
		s waitForConnectionFor: Socket standardTimeout ifTimedOut: [].
	].

and when I run this code the result is 1.
	| addr s |
	Socket initializeNetwork.
	MessageTally tallySends: [
		addr := NetNameResolver addressForName: 'www.google.org'.
	].
	addr

I hope this helps,
Rob
