Leap year bug crashes Zune

Microsoft’s 30GB Zune players fail to work today (Dec 31).

The problem has been identified - A bug in the freescale firmware leads to an infinite loop on the last day of a leap year.

year = ORIGINYEAR; /* = 1980 */

while (days > 365)
{
   if (IsLeapYear(year))
   {
      if (days > 366)
      {
         days -= 366;
         year += 1;
      }
   }
   else
   {
      days -= 365;
      year += 1;
   }
}

If such poor codes were found in an airplane, or a medical device, ooops, it should be terrible..
