Comment #14 on issue 2815 by [email protected]: Patch: parser/lexer: de-unionize semantic values, make all of them SCM
http://code.google.com/p/lilypond/issues/detail?id=2815
Those tests point to the latest commit by Mike regarding spanbars. They don't really have anything to do with my code.
If you did not accidentally associate them with the wrong patch or Patchy messed up, it would appear that Mike's work renders cross-staff slurs non-deterministic.
