Yes, after looking through the code a bit more thoroughly, I believe
that memory had been allocated in another method when the pointer was
However, I'm still curious as to what may happen if 'delete' is called
on a pointer that is created locally without the 'new' operator ever
being invoked.
Any thoughts?

	This is fine as long as the pointer "head" has been allocated
	"new" sometime in the past, peharps in another call when the
