I think this may be a cultural thing. C programmers are very much used to the standard not defining the behaviour of some things, e.g. what happens when you call strcmp(str, NULL). Segfaulting is expected here, and easy to track down. (I would use some assert()s if a function could cause silent memory corruption; but this particular function either works (valid string), segfaults (NULL) or cannot detect a problem (stray pointer).)
