What version of dnsmasq?

hostname_isequal is used in quite a few places and should never be
passed a null pointer, so in my opinion the fix is a sticking plaster
over the issue and has the potential result of leaving null pointers
hanging around for other functions to fall over anyway. The root cause
should be found and squished. Any idea which particular call to
hostname_isequal was involved?
