Wierd free() problem.

It *is* a problem in your code. To see it, I suggest that you compile
with -lmcheck, which will give you a diagnosis from malloc.

The problem is that you are overwriting the internal malloc data
structures when writing beyond the end of a buffer in a call to#

				strcpybck(Start + withLength, Start + Length);

which in turn originates from

		      this -> Buffer.Replace(start, (end - start) + endLength, (char *)listBuffer -> Buffer);

Hope this helps,
Martin
