Martin,

I am sorry that I do not have a system where this code actually
triggered a problem, since this bug is discovered by a *static* analysis
tool that is recently developed by our research group, which finds code
segments that are similar to a previously fixed bugs as potential bugs.
 You are saying that if I pass a long to the i argument parser it will
cause a problem. But if I passed a int, it will be same as before and
overflow will not be detected at all.

Victor,

Do you also agree that it will cause a problem if I pass a long to the i
argument parser? If so, I think maybe the overflow problem cannot be
solved by the patch I submitted.

Boya
