I am trying to combine to language models with mitlm, but I am running into
problems loading some 3rd party arpa files into mitlm. I get this error every
time: 

interpolate-ngram: src/NgramModel.cpp:329: void NgramModel::LoadLM(std::vector<DenseVector<double>, std::allocator<DenseVector<double> > >&, std::vector<DenseVector<double>, std::allocator<DenseVector<double> > >&, ZFile&): Assertion `p >= &line[lineLen]' failed.
Aborted

There are two open issues in the repo related to this:
http://code.google.com/p/mitlm/issues/detail?id=27
http://code.google.com/p/mitlm/issues/detail?id=30

I've seen quite a few examples of people using mitlm on arpas like the
"lm_giga_5k_nvp_3gram.arpa" with success, but I have not been able to
successfully do it yet.

I've been following the example on this blog:
http://nsh.nexiwave.com/2011/04/voicemail-transcription-
with.html

Is there a specific revision number of mitlm I should be using to do this. Has
anyone else successfully done it?

Thanks!
