If we reached the line "unsigned short *p = (unsigned short*) data;" then ''data" is definitely null and "n" is definitely >0, otherwise we would take the early return branch. Then we have "p" is definitely null and "q" is either equal (if n == 1) or greater then "p". In case of n > 1 we definitely have a null dereference. Please tell what I'm missing.
