Bugzilla Bug 155258

There is a known major bug with libvorbis-1.1.0's encoding quality
and GCC 4.x when GCC does any optimization whatsoever.  The Oggs
encoded with this broken libvorbis sound really, /really/ bad.  I
can provide samples of the difference between a qual 3 ogg in the
broken encoder and the same song encoded with a non-broken one.

Xiph discovered this issue and fixed it in libvorbis-1.1.2, which
has been ~x86 for a while.

It would be nice to not have our users encoding lots and lots of
really crappy Oggs, whether through a backport of the patch that
fixes the bug or a (seemingly safe; I reencoded something like
1000 Oggs overnight to replace ones that had the skeevy sound)
version bump.

May be it's time to have 1.1.2 stabilized.
In bug #149855 , Flameeyes stated that he doesn't want to stabilize it unless
there is a reason.
Maybe this bug is the reason.
libvorbis 1.1.1 & 1.1.2 are mainly bugfix releases, see:

So, arch teams, that's up to your decision now :)

media-libs/libvorbis-1.1.2  USE="-aotuv"
1. emerges on x86
2. passes collision test
3. revdep-rebuild doesn't show anything broken
4. xine-lib and vlc emerge fine with this version and play ogg

Stable on ppc

libvorbis-1.1.2  USE="-aotuv" looks good for me too on x86. i'm still able to
play
ogg files using audacious-1.2.1 and the files i've just ripped from a cd to ogg
using sound-juicer-2.14.4 are fine.

Playing on x86

sparc stable.

I've been running with this version of the library ever since I posted the bug
with no problems whatsoever, encoding tracks, listening to them via XMMS and on
the command line, and so on.  I'm running x86.

Stable for HPPA.

ppc64 stable

Alpha stable.

amd64 stable

Marked stable on MIPS.
