I'm afraid something went wrong with the generation of band_struct. Could you not post this part of code?
I suggest replacing the struct generation temporarily with something very simple thing like this

octave_scalar_map band_struct;
band_struct.assign("answer", 42);

and checking whether it crashes. I use a very similar code-structure as you do, except I assign my structs to an octave_value_list.
Note, there is a more appropriate type for index variables: octave_idx_type.
