It looks like you've run into an overflow issue here. Unfortunately iota-calc is stuck using signed 32bit numbers for many of its operations, and can only compute the & operator up to x7fffffff. Ideally we would like to add support for at least unsigned 32bit numbers or better yet 64bit and beyond. Unfortunately I can't promise when (or if) that will happen.
