Maybe there’s a race against the garbage collector.  Did any recent changes to 
the C++ add SCM things but overlook handling the reference count?  Does the 
behavior change if you force garbage collection (scm_gc()?) at key times in the 
course of engraving? say, right before calling the callback that has been 
behaving inconsistently?
