Comment #7 on issue 1609 by address@hidden: unpredictable change of  
voicing
http://code.google.com/p/lilypond/issues/detail?id=1609

Regtest change pushed in 6afd86a9b, to appear in 2.15.0

Note that the pushed change only prevents a regression test from generating  
a .ly file that produces varying typeset output.  This problem was, I  
think, the critical aspect of this issue.

As the examples above illustrate, placement of such rests still changes  
unpredictably.  The score in example 2 produces different output with the  
two command lines
 lilypond test.ly
 lilypond test.ly test.ly
while version 2.12.3 produces the same output in either case.  Both  
versions produce a warning "too many colliding rests".  See also issue 1547  
and issue 384.
