lilypond crash in special case

[Leo Naab]

> I'm not top posting.

I have a special lilypond file with let's lilypond.exe crash. The file works
fine with version 2.19.15, but not with 2.19.17.

The crash has do to with a "\new Lyric" line. "\new Lyric" in \context Staff
didn't work, but if the "\new Lyric" comes behind the \context Staff all is
fine.

I reduce my lilypond file to the following:


\version "2.19.0"

sopranMusic = \relative c' {
        %fis1 e1 fis1
        r1 r1 r1
}


bassMusic = \relative c'' {
        %e2~ e4.( fis8 ~ fis1) g2( a4. d,8) \break
        a4 a8 g8~ g8 g4 fis8~ fis8 fis4. r8 g8 g8 g8 a4 a8 ais8~ ais8 ais4 
fis8~ \break
        fis1 a1 fis1 a1
}

bassWords = \lyricmode {
        %uh uh
        Er ist das Zen -- trum der Ge -- schich -- te. er ist der An -- ker
}


\new ChoirStaff <<
  \context Staff = "Sopran" <<
                \new Voice = "Sopran" {
                        \sopranMusic
                }
        >>
        \context Staff = "Bass" <<
                \new Voice = "Bass" {
                        \bassMusic
                }
