Thanks for your report. What version of Nmap do you have installed?
Shortly after 5.00 was released, I made a change that should make Ndiff
require less memory. Unfortunately at this time you will have to get the
latest version from Subversion.

A core dump is strange because Ndiff is a Python program. I would expect
a Python MemoryError. What is the exact output that you see?
