Any idea what would cause it to do that?
Possibilities that jump to mind:
1) Heap corruption (are you stepping outside some array bounds somewhere?)
2) Using uninitialized variables (are you expecting a variable to be initialized with 0 even though you never explicitly set it to 0?)
How about I didn't even touch the method that controls that output, but I added a new method and recompiled. Now it looks like this:

Strange huh?
Irrelevent changes having an effect on program output smells of heap corruption. I stand by my earlier post.
