This codepath would only be reached if the buildsystem determined that memset_s
was available so something is fairly wrong here. Did you change any builfiles
after running configure? Re-install or upgrade XCode after running configure?

memset_s and memset have the same prototype, and are functionally equivalent,
but memset_s have certain properties which are required in this codepath.
