You were correct. I put that code into its own program and it ran just 
fine.. so I'm not sure what the deal is in my test cases, I don't know 
why it would kill the output since its basically the exact same code. 
This is the strangest thing I've seen in a while and I really have no 
idea what might be the problem.
