Complete minimal working example, omitting the lower staff:
\version "2.16.2"
sopTxt = \new Lyrics = sopL \with { alignAboveContext = "upper" }
\lyricsto sop \lyricmode { A C }
sopV = \relative c'' { << { c2 c } { \sopTxt } >> c4 c c c }
altV = \relative c' { c4 c c c c c c c }
\score {
\new ChoirStaff <<
\new Staff = upper <<
\new Voice = sop { \voiceOne \sopV }
\new Voice = alt { \voiceTwo \altV }
>>
\new Lyrics \lyricsto alt { A B C D E F G H }
>>
}
Where are the four c4 notes of the soprano?
This may be a bug. Copying to the bug list.
Removing \lyricsto restores the missing notes, so as a work-around,
given you have just one bar, remove \lyricsto and enter the duration
of each syllable explicitly.
