I'm not sure whether we do want sanity checks at all.  After all, this
is all pilot errors (people forgetting to check whether their buffers
or FILE * are NULL), but by adding sanity checks, a penalty will be
imposed on anyone using these functions, including those who used it
correctly.

Unfortunately, I didn't find any conclusion in the C standard whether
the behaviour in these situations might be implementation-defined or
undefined.  Maybe ask in comp.lang.c?
