If you pass a null pointer to a function that does not expect one, the
result is undefined. If the process is not terminated, its state
(including errno and any register or memory contents) may be set to
any value whatsoever.
If it were me, and I for some reason wanted to check this corner case
explicitly, I'd use [EFAULT].
