I had installed libvorbis-dbg as you can see.
The line 1905 of vorbisfile.c :

$ more +1901 -8 libvorbis-1.3.2/lib/vorbisfile.c 

    long channels=ov_info(vf,-1)->channels;
    long bytespersample=word * channels;
    vorbis_fpu_control fpu;
    if(samples>length/bytespersample)samples=length/bytespersample;

    if(samples <= 0)
      return OV_EINVAL;

Thanks!
