New issue 1139 by brownian.box: 'inter-loose-line-spacing #'stretchability  
leads to collision under some conditions
http://code.google.com/p/lilypond/issues/detail?id=1139

Sorry, snippet rather long; there is no collision if stripped to three  
notes.

If this can help: 2.23.24-2 engraves this example in the same way, but real  
score which contains this part, looks good with 2.23.24.

alto = \relative d' {
  \autoBeamOff

  g4 g g g |
  g1 ~ |
  g4 c,8 c c4 c |
}

tenor = \relative b {
  \clef "bass"
  \autoBeamOff
  %
  e4 d c d |
  e4 g,8 g g4 g |
  g1 |
}

altolyrics = \lyricmode {
  \repeat "unfold" 5 { \skip 1 }
  по -- пе -- че -- "ні -" % -- є.
}

commonlyrics = \lyricmode {
  по -- пе -- че -- ні -- є,

tenlyrics = \lyricmode {
  \repeat "unfold" 5 { \skip 1 }
  по -- пе -- че -- ні -- є,
