You are right; my test was flawed.  However, it doesn't happen exactly the
same for me.  I seem to get 56 extra bytes, not 12.

Confirmed that the problem does not occur with the CVS version.

There is a bug in 1.0 (later discovered) for raw input that
crept in when souped up the wave autodetector.  It adds
duplicate samples to the beginning of the encoded file.
I can't seem to find the original thread in the flac-dev
archives.
