so you're saying it worked as expected with -8 but not
with -6? (the default compression option). that would
be very wierd.
however there is a bug that happens in this case
where stuff is added after the end of the data chunk
without using another WAVE chunk. I've committed the
fix (in src/flac/encode.c). it should now ignore
anything after the end of the data chunk.
