Adding GCDAsyncSocket to existing code problems

[hvolmer]

I must prefix this by thanking everyone involved in creating
AsyncSocket over the years. It's been very handy!

I'm pretty hung up on adding GCD.. to an existing iOS project. I have
a tiny class that is responsible for managing each client
GCDAsyncSocket. It connects to a test server for me.

What happens: Compiles fine. The GCD client connects and then my app
immediately crashes in the iOS Sim.

If find it dies in: - (BOOL)connectWithAddress4: with [self
didConnect:aConnectIndex]; highlighted. I'm not very good at reading
these failures or I would provide more information...

I have even copied all of the code from the ConnectTest sample project
- no luck. The ConnectTest project fine by itself. I've even pointed
the ConnectTest project at my server and it works fine. I thought
that this might have something to do with ARC (I have set the -fno-
objc-arc flag on the GCDAsyncSocket file), so I converted the
ConnectTest project over to ARC, using XCode's handy tool, and it runs
fine also.

What should I look for? Is there some sort of trace I can provide
that might help? I've attached pretty much everything GCD.. related
below. Thanks.
