Comment #6 on issue 2067 by address@hidden: Patch: Give \displayLilyMusic and  
\displayMusic optional port arguments.

That patch does not just touch page breaking, but it also introduces Grob  
arrays.  My patch, in contrast, is Scheme-only, and there are quite limited  
possibilities for Scheme-only code (apart from triggering bad C++ code or  
violating assumptions underlying C++ code) to cause error messages like  
that.

So Mike: can you recheck your 5ac2664c2207e8dfa1734d786e5c7b214b275521  
checkin using --no-optimize or whatever else it was we used to check for  
undead objects?
