Thanks. I added the following to our bug repository.

Question is whether the third alternative (C) in this example should be 
written out or not. I would guess that it should be rewritten, to avoid 
confusion (it is hard to remember things across volta brackets, and it 
doesn't cost much to add a reminder). Comments are welcome.

(I suppose that it would be easier to code this also, just clear the 
chordChanges memory in the beginning of each alternative)

\version "2.2.4"
\header {texidoc = "
Chord names are sometimes repeated incorrectly under \\alternatives.

Both G:s, but possibly not the C, should be shown.

\score {
  \new ChordNames { \set chordChanges = ##t \chords {
    \repeat volta 3 { c1 }
      \alternative { {g1} {g1} {c1} }
  \new Voice \notes {
    \repeat volta 3 { c1 }
      \alternative { {g1} {g1} {c1} }
