; You can calculate where the next frame will start depending on things
; like the bitrate. See mad_header_decode(). It seems that when decoding
; the frame you can go past that boundary. This attempts to catch those cases,
; but might not catch all of them.
; For more info see http://bugs.debian.org/508133
