yet another vorbis issue
    vc->audio_channels=get_bits(gb, 8);   //FIXME check >0
    vc->audio_samplerate=get_bits_long(gb, 32);   //FIXME check >0

<=0 are clearly invalid, a check should be added for that ...

Into a blind darkness they enter who follow after the Ignorance,
they as if into a greater darkness enter who devote themselves
to the Knowledge alone. -- Isha Upanishad
