No, octave also crashes if I retrieve the data and then initialize 
audioplayer :

ar = audiorecorder ();
record (ar, 2); # recordblocking makes no difference
y = getaudiodata (ar);
ap = audioplayer (y, ar.SampleRate);
play (ap);


Sometimes it's a "segmentation fault: 11", sometimes a "bus error: 10".
