Here's a minimal snippet:

\version "2.12.3"
<<
  \new Voice = melody { c4 c8 }
  \new Voice = tenorVerses { c2 }

  \context Lyrics = foo \lyricsto dummy {
    la
  }
  \context Lyrics = foo \lyricsto melody {
    la __
  }
>>

The extender triggers an infinite loop in Context::now_mom (), since
the Voice it's associated with for the first Lyrics block rather
mysteriously has no parent context.

Several extender bugs were fixed in recent 2.13 releases, but I don't
think we can backport them since there's unlikely to be another 2.12
release.

Cheers,
