Hello,
attached patch fixes a crash when pred_order > s->blocksize >>
rice_order, as exposed by http://sam.zoy.org/zzuf/lol-mplayer.flac
Since I do not know the spec i have no idea if this patch is the correct
way to fix it though (though it is very simple and looks like it could
make sense).

Greetings,
Reimar Doeffinger
