The consensus in the C community is that adding such checks does more harm than good, because a NULL pointer is usually a symptom of a bug somewhere else in the application, and checking for a NULL pointer will either hide that bug or trigger another error somewhere down the line, possibly making the real bug harder to find, rather than easier.
