SigWinchHandler is a class, so you have to create instances of the class  
with new. In your main function "SigWinchHandler winch;" just sets winch  
to null and in the connect call you access winch.handler which causes the  
crash. What you need to do is "SigWinchHandler winch = new  
SigWinchHandler();" and the same for SigAlrmHandler.
