you mean the github version of mgiza?
  https://github.com/moses-smt/mgiza
Compared to what old version from where?

I need to know what u ran and the corpus you ran. I'm not an expert on mgiza so my debugging is as good as yours in this area

Sorry, I emailed from the wrong address.

The error is consistent irrespective of the dataset. My old mgiza installation is producing the correct results. This problem is only with the recent build of mgiza.

    What was the exact commands you ran? Can you try and run it on a
    small corpus and make the corpus available for download so people
    can reproduce the error

        Hi,

        There is an issue with the recent release of mgiza. It either
        crashes or produces wrong alignments which are either all
        words aligned to NULL or every source word aligned to every
        other target word.

        Following is the tail of STDOUT file where model4
        cross-entropy is -nan.

        #peggingImprovements: 0
        A/D table contains 0 parameters.
        A/D table contains 0 parameters.
        p0_count is -nan and p1 is -nan; p0 is 0.999 p1: 0.001
        Model4: TRAIN CROSS-ENTROPY nan PERPLEXITY nan
        Model4: (6) TRAIN VITERBI CROSS-ENTROPY nan PERPLEXITY nan

        Model4 Viterbi Iteration : 6 took: 16 seconds
        3333444 Training Finished at: Thu Jan  8 10:02:45 2015
