Details:

I accidentally found that when writing to a mono (1 channel) OGG file, if the
data is long enough, then Octave will crash with signal 11 (Segfault).  For
example,


octave:2>  audiowrite ("1.ogg", rand(2000000,2), 44100)
octave:3>  audiowrite ("1.ogg", rand(2000000,2), 8000)
octave:4>  audiowrite ("1.ogg", rand(2100000,2), 44100)
octave:5>  audiowrite ("1.ogg", rand(2100000,2), 8000)
octave:6>  audiowrite ("1.ogg", rand(2000000,1), 44100)
octave:7>  audiowrite ("1.ogg", rand(2000000,1), 8000)
octave:8>  audiowrite ("1.ogg", rand(2100000,1), 44100)
fatal: caught signal Segmentation fault -- stopping myself...
Segmentation fault

octave:1>  audiowrite ("1.ogg", rand(2100000,1), 8000)
fatal: caught signal Segmentation fault -- stopping myself...
Segmentation fault
