Well, the syntax you've used here is assigning "BitsPerSample" to the
variable audio_prop, and then just evaluating some other values but not
assigning them to anything. Your sample code is equivalent to this:

  audio_prop = "BitsPerSample"
  ## some values that are not assigned to anything
  audiowrite("/tmp/test.wav", data, 44100, "BitsPerSample")

You probably want something like

  props = {name1, value1, name2, value2, …};
  audiowrite (filename, data, sample_rate, props{:})

Look through the Octave manual for usage of cell arrays and
variable-length argument lists.

But yes, the crash is a bug, please help and file a bug report if you
can.
