What kind of shitty programming can result in "you won $41Mil" when the max is $6500?

Certainly a couple range/integrity/sanity failsafes could have been implemented?

Two people had good guesses above:

&gt;Interesting! It would seem at first glance that the glitch caused a 32-bit integer overflow, which would wrap around the jackpot value to 4,294,967,295 cents, or 42.9 million dollars.

&gt;I think it's more likely that a faulty component shorted and powered all the pins on a 32-bit bus - 111111111111... would yield that result.
