Don't do that, then?

It's supposed to be passed a zero-terminated string, so it doesn't seem
unreasonable for it to assume that it can dereference its argument. The C
library functions don't in general accept NULL pointers as string
arguments.

I suppose a check for NULL would be fairly harmless, though.
