It's likely that you are using global variables (as a general thing that is bad) that are not getting initialised before main is called. Try moving all global variables into main - that will break stuff and mean that you have to pass the variables to any sub that needs them, but that is a good thing!

If that doesn't match with your code, show us the code or at least a stripped down version that demonstrates the issue.
