If you replace the a!0 in f by its value 0, f is equivalent to:

            f k = if k > 0
                    then f 0
                    else 0 : f 1

Do you see the loop now?

Maybe you meant f to be:

            f k = if k > 0
                    then f (a!k)
                    else 0 : f 1
