New issue 1715 by address@hidden: Ligature and ambitus cause  
segfault
http://code.google.com/p/lilypond/issues/detail?id=1715

The code below bombs with a segmentation fault in lilypond
2.14.1.

If you comment out either the ambitus_engraver or the stuff about the
ligature engraver, it compiles as expected.

Same problem with 2.12.3

\version "2.14"
testnotes = {
  \relative c' {
    \[ c\longa c'\longa \] %This is a ligature; we are interpreting it as  
two whole notes
  }
}
\score{
  <<
        \context Staff="default"
        {
            \testnotes
        }
  >>
        \layout {
          \context{
                \Voice
                 \consists Ambitus_engraver
                \consists Mensural_ligature_engraver
          }
  }
}
