New issue 3617 by address@hidden: Compilation error when using  
stemlet over rests
http://code.google.com/p/lilypond/issues/detail?id=3617

LilyPond is unable to compile the code below, outputting the following  
message: "Exited with return code -1073741819"

\version "2.17.28"
{
  \override Staff.Stem.stemlet-length = 0.75
  \clef percussion
   a,8->[ r8  c''8 r8 a,8 r8 c''8]
}

Apparently, there is some conflict between the position of the rests and  
the stemlets. This is due to the fact that the gap between the notes in the  
code above allow knee beaming.

The code above compiles if kneed beams are disabled by:
\override Beam.auto-knee-gap = ##f

For the record, LilyPond is able sometimes to lower the rests further down  
when dealing with the kneed beams, thus allowing enough space for the  
stemlets and so everything works well:

\version "2.17.28"
{
  \override Staff.Stem.stemlet-length = 0.75
  \clef percussion
   a,8->[ r8  c''8 a,8]
}
{
  \override Staff.Stem.stemlet-length = 0.75
  \override Beam.auto-knee-gap = ##f
  \clef percussion
   a,8->[ r8  c''8 a,8]
}
