New description:

 When allknn_main tries to initialize it's AllkNN, a failure occurs.

 NeighborSearch initializes an armadillo matrix with a null character
 pointer (see Mat_meat.hpp:197) which results in failure.

 This also in allkfn_main and allknn_main.
 The error can be reproduced by passing in a valid k, reference file,
 neighbors file, and distances file.
