Comment #1 on issue 1972 by address@hidden: Seg fault and 100% CPU when  
using \override Staff.StaffSymbol #'ledger-positions
http://code.google.com/p/lilypond/issues/detail?id=1972

% this also produces stuck 100% CPU at 'Drawing systems...'

\version "2.15.13"
\relative c' {
  \override Staff.StaffSymbol #'ledger-positions = #'(1 1 1)
  f''4 a a,, f
}

% this works

\version "2.15.13"
\relative c' {
  \override Staff.StaffSymbol #'ledger-positions = #'(1 2 1)
  f''4 a a,, f
}
