LilyPond regression on simple file

[Basil Crow]

Based on an example from the documentation
====
\version "2.5.29"
melody = \relative c' {
 \clef treble
 \key c \major
 \time 4/4

 a b c d
}

text = \lyricmode {
 Aaa Bee Cee Dee
}

harmonies = \chordmode {
 a2 c2
}

\score {
 <<
    \context ChordNames {
       \harmonies
    }
 \context Voice = one {
    \melody
 }
 \lyricsto "one" \new Lyrics \text
 >>
 \layout { }
}

LilyPond 2.5.27 compiles it perfectly.
