I added INVARIANT_SUPPORT and INVARIANTS options to the GENERIC
kernel, rebuilt it, installed it and running through my "test case"
generated a lot of invalid flac files.  I"m not sure what the options
are/were supposed to do though, it looks like they generally lead to
KASSERTS, which lead to abort()'s.  Nothing in /var/log/messages or on
the console.
