[Octave-bug-tracker] [bug #50674] audiorecorder() crashes in getaudiodata()

[Rik]

Follow-up Comment #1, bug #50674 (project octave):

I used a slightly modified program which I have attached.


more off
recorder = audiorecorder ()
record (recorder)
for i=1:20
  printf ("############################################################\n");
  printf ("Executing Loop #%d\n", i);
  printf ("############################################################\n");

  pause (1);

  get (recorder)
  printf ("executed get (recorder)\n");

  data = getaudiodata (recorder);
  printf ("got data\n", i);

  size (data)
end
stop (recorder)


Here is a backtrace from gdb, also attached.

There is a double free or other corruption in malloc from the getaudiodata
call.
