Unreasonable Size Argument

Multiplication Overflow of Size

Subtraction Underflow of Size

Could detect violations of this recommendation by flagging any comparison expression involving addition that could potentially overflow. For example, instead of comparing a + b < c (where b and c are compile-time constants) and b > c, the code should compare a < c - b. (This assumes a, b, c are unsigned ints. Usually b is small and c is an upper bound such as INT_MAX.)
