I'm not an expert at Visual Studio, but is it possible that the function
`mlpack::data::Load()` is actually compiled inside of mlpack.dll, and
there are no debugging symbols available?

You might be able to fix this by recompiling mlpack with debugging
symbols.  But, I don't know exactly how to do this with Visual Studio.
