Tests fail

[minhlab]

I downloaded and built OxLM today and two tests failed. What should I do now?

[  FAILED  ] MaxentSGDTest.TestTrainMaxentNCEExtractedNGrams (2410 ms)

I was using CentOS Linux 7.

When I run it on real data, I got this error:

Turns out that I need to specify hash-space (default is 0 which causes division error). A meaningful error message would be useful.
