My first suspicion was that it was just overflowing, but not getting
the message out. I just realized that my latest testing (the last 24
hours) was on the original patch, not the updated one that you posted
later, which included the stack checking. I'm sure that I was having
the same problem with the overflow checking enabled and _not_ getting
any errors from it, but I'll redo the testing for my sanity's sake.
