Confirmed, the diagnostic says it is controlled by -Wnonnull, but that's not a
valid option for G++

extern void *f (void *__s) __attribute__ ((__nonnull__ (1)));

int main()
{
    void* const s = 0;
    f(s);
}

w.cc:6:8: warning: null argument where non-null required (argument 1)
[-Wnonnull]

For G++ that warning is controlled by -Wformat/-Wno-format
