What it is

The product performs a calculation that can

produce an integer overflow or wraparound when the logic

assumes that the resulting value will always be larger than

the original value. This occurs when an integer value is

incremented to a value that is too large to store in the

associated representation. When this occurs, the value may

become a very small or negative number.
