Integer Overflow in Voting Machines

Seen in Wired:

There were also problems with machines that counted absentee ballots in Florida. Software made by Election Systems & Software began subtracting votes when totals surpassed 32,000.

Item no. 9 from this list may be relevant here.

UPDATE:The same bug changed at least one election result.

UPDATE 2:The manufacturer of the machine has confirmed my conjecture.

    Wouldn’t that be 32767?

    TOndrej, yes, most likely. I think the total in the article was an estimate.
