Yes, that's how I fixed it. Uncommenting that line in arma's config.hpp before running cmake/make/make install for mlpack
The code that goes wrong in the application is a call to:

    mlpack::regression::LogisticRegression<> fit(x_train.t(), y_train)

where x is a 200x3 arma::mat and y is a 200x1 arma::vec

Otherwise I think I've put all the information I can above. I think it's an installation issue rather than the application. Perhaps the state of `ARMA_64BIT_WORD` is incorrectly detected

Installing as above, followed by such a call should reproduce the error. If it doesn't, or it is difficult to follow the exact same steps, I'm happy to close this as solved/fixed!
