The correct format specifier for p - n (both p and n are pointers) is
%td, as the type should be ptrdiff_t.
This was discovered by annotating KUnit assertion macros with gcc's
printf specifier, but note that gcc incorrectly suggested a %d or %ld
specifier (depending on the pointer size of the architecture being
built).
