If the high bit in a mask is set, for instance if the mask is 0xff000000, and we shift it to the right by 24 positions, since the mask was not declared as unsigned we ended up with a mask value of 0xffffffff. We then add 1 to this value and divide by the result, causing a division by zero crash. The masks need to be declared unsigned to prevent sign bit extension when shifting right.
