       cc1: Exit when we cannot discard
       
       If the input parameter is null then we don't have any input
       that we can discard, and it just generates a segfault because
       the for loop assumes that the input parameter is different
       than 0, but it still checks if it can ask for more input
       using the function moreinput().
