-1 array index in ArrayCompare

[mtholdefer]

I am running into an issue when I run your implementation of the fuzzy hash comparison. The idx2 parameter of ArrayCompare() is being passed in as -1, and then trying to reference data at index -1. This obviously crashes the program. I thought you might be interested in this issue, as when I run the ssdeep comparison in C on the same hashes it finds a match with score of 60 and does not crash.

The two hashes are:

384:Y2yjcXqXJ64g1WG8jWEMsKf9bfdkFtbH2:Yrjc6564wWT2sKf9b1kzC
192:lKEtF3iJUeF9dPdCmhsqMUGzw6c9PY1fR/rA:Y2yjcXqXJ64g1m

Hi Matthew,

I'm not making changes on SSDEEP so soon because we stopped using the algorithm in preference of TLSH that you find on this location: https://github.com/triplecheck/tlsh

There is a syntax example on https://github.com/triplecheck/TLSH/blob/master/sources/Test.java

Hope this helps,
Nuno
