EXC_BAD_INSTRUCTION on random Int between Int.min and Int.max

[phimage]

When developing a feature about Lattice (ordered with min and max bound) for RandomKit
https://github.com/phimage/RandomKit/blob/feature-lattice/RandomKit/RandomType.swift
after doing one for my maths project
phimage/Arithmosophi@e4db5e2

an issue occurs.

Doing random on min...max range of a Int (and other type) failed with EXC_BAD_INSTRUCTION

A test to add to check this error

    func testRandomIntMax() {
        let min = Int.min
        let max =  Int.max
        Int.random(min...max)
    }

The EXC_BAD_INSTRUCTION is due to the overflow when subtracting Int.min from Int.max. I'm not sure of a way around it.
