[mlpack-git] [mlpack] segmentation fault with LogisticRegression API (#428)

[Ryan Curtin]

That warning doesn't indicate that failure will occur; that warning only indicates that `ARMA_64BIT_WORD` is not enabled in the Armadillo configuration, so very large matrices (with more than 2^32 elements) cannot be used.  The warning that should be issued if mlpack was compiled without `ARMA_64BIT_WORD` and a program is being compiled with `ARMA_64BIT_WORD` reads this: (from `src/mlpack/core/util/arma_config_check.hpp`):

```
mlpack was compiled without ARMA_64BIT_WORD, but you are
compiling with ARMA_64BIT_WORD.  This will almost certainly cause irreparable
disaster.  Either disable ARMA_64BIT_WORD in your application which is using
mlpack, or, recompile mlpack against a version of Armadillo which has
ARMA_64BIT_WORD enabled.
```

Did you not see that warning when you compiled?  If you didn't, then maybe I need to do some debugging and figure out why...
