Issue 380: cycling markup reference segfaults
http://code.google.com/p/lilypond/issues/detail?id=380

Comment #8 by gpermus:
Ugly hack:

whenever you use foo = \fromproperty #'bar, you add "foo, bar" to a global list 
of
"references used".  Whenever you see a \fromproperty #'baz, you check to see if 
"baz"
is mentioned in the global list of references used.  If it is, exit with an 
error.

You probably only need to store one of foo/bar, though.  I'd need to work it 
out on
paper to figure out which one, though.  (I do all my math with a pencil :)


I'm not proposing this as a serious suggestion, though.  This is too ugly, and 
IMO
not worth the trouble.  If somebody is playing with \fromproperty, then they 
should
be able to fix their own ly files to avoid these crashes.
