I am using Swift to generate some tests with overflowing 32-bit integers. I have used the Int32.<op>WithOverflow functions but have come across a problem dividing Int32.min by -1 with overflow. I get an overflow error:
error: division '-2147483648 / -1' results in an overflow
Int32.divideWithOverflow(Int32.min, -1)
which is to say that the result of the division can't be expressed as
an Int32.
