Details:

Executing this script hangs Octave after few iteratons and leaves it stuck at
100% CPU, both in GUI and on commandline. 


recorder = audiorecorder ()
record (recorder)
for i=1:60
  pause (1)
  get (recorder)
  data = getaudiodata (recorder);
  size (data)
end
stop (recorder)


CTRL-C then terminates the GUI. On commandline this info is shown:


^C^C^Cfatal: caught signal Interrupt -- stopping myself...
attempting to save variables to 'octave-workspace'...
error: octave_base_value::save_binary(): wrong type argument 'audiorecorder'
terminate called after throwing an instance of 'octave::execution_exception'
octave exited with signal 6


I wonder if it is hardware dependent, a portaudio thing or Octave?
