New issue 1296 by v.villenave: Progerrors when using \laissezVibrer in a
cross-staff context
http://code.google.com/p/lilypond/issues/detail?id=1296
% Reported by Neil on -devel:
http://lists.gnu.org/archive/html/lilypond-devel/2010-09/msg00064.html
% The following example produces unobjectionable output, but
% spits out programming errors:
\version "2.13.33"
<<
\new Staff = "up" \relative c'' {
c8
\change Staff = "down"
c,8\laissezVibrer
\change Staff = "up"
c'8 c
}
\new Staff = "down" { s2 }
%%%
Neil reported the following progerrors with 2.13.33:
-> programming error: cyclic dependency: calculation-in-progress
encountered for #'direction (Stem)
Whilt 2.13.35 gives me the following:
Grob direction requested while calculation in progress.
Neil:
"""
In a real score, it's more serious, since it's preventing automatic
kneed beams from working; in this case the (voluminous) errors are for
adjacent-pure-heights:
-> programming error: cyclic dependency: calculation-in-progress
encountered for #'adjacent-pure-heights (VerticalAxisGroup)
"
Neil suspected that this was caused by the fix for issue 881, which would
make it a regression.
