If you want to always get a SEGV when the user passes a NULL argument, you
will have to arrange that through your code. POSIX doesn't guarantee you a
SEGV here.

90% of your users, at least, will be on glibc systems. On these systems
gnulib's code is not used, the glibc code is used. How would a configurable
behaviour of the gnulib code help you?
