Sorry, I saw your reply first now. I am not sure exactly what part  
you have in mind, but I have made a new version, updated to latest  
Lilypond, which strips out some of the unnecessary stuff.

The bug shows up in meters 7/16 and 11/16, and perhaps in any meter  
where the beaming between 1/16 notes do not fall within 1/8 parts  
divided up from the start of the measure (i.e., the first 1/16 the  
pair to be tied does not have an odd count if the first 1/16 of the  
measure is given count 1). In the example, the counts within the  
measure of the 1/16th notes paris are: 6 and 7; 24 and 25.

The example contains just one (compound) measure. So I am not sure  
how it should be simplified further. - It shows up in some other  
music, when I recompile it, but I am not sure exactly when. So I  
think this is the best example.
