It's known in the sense that you and other people have repeatedly
reported it, but not known in the sense that the developers have never
observed it. Are you POSITIVE it's not related to your version of
mp3lame or perhaps to a broken version of gcc? If you haven't tried
downloading lame tarball and compiling it yourself manually, DO THAT.
And make sure you don't have an old/broken copy lying around that's
getting used instead of the new one.
