My thinking on that was that for most people calling the free()
functions on a null pointer is usually an error rather than by design,
so it's helpful to get a segmentation fault.  

In general, I've never been convinced that free'ing a null pointer is
particularly useful as opposed to just doing "if (p) free(p)" in the
application.
