Look like the old code has a flaw:

  for (int k = 0; k < noutput_items; k++){
    ...
    out_sample[k] = interp_sample;
    ...
  }

  return k;




but modern compilers deallocate the index when the loop
is completed (one web page says), so the fix is to use:


  for (int k = 0; k < noutput_items; k++){
    ...
    out_sample[k] = interp_sample;
    ...
  }

  return noutput_items;
