It clearly looks like a bug, so why didn't you send it to bug-lilypond (as you notice, I include a copy to that list). It's a long time since we discussed the use of the mailing lists, but if I recall correctly, the idea of the lilypond-development list was to use it to discuss the development versions and use lilypond-user mainly for issues on the stable versions and general questions. Finally, it's rather a change in the semantics (what happens) than in the syntax (how it's described).
A few minor comments on you example: - Why not exploit the fact that in the << voice1 \\ voice2 >> construct, voice1 will automatically get \stemUp and voice2 will get stemDown? - If you use \once \override ..., you won't need the \unv macro, at least not in this particular example. - In the upper voice, you can replace the invisible notes with spacer notes 's', to save some typing. However, none of these details affect the bug you found.

In a slightly earlier version the following snippet produced what I wanted. That is, six eighth-note triplets; three pointing up and three pointing down and intermeshed like this:

With slurs/ties conneting adjacent note heads.
Now, in version 2.1.23 the noteheads on the up stems are invisible. Is
this due to a change in the way contexts are handled, or is this a bug? This version was compiled from CVS ChangLog 1.718.
Thanks,
