Yes you are correct.

However if I have 3 scores using 3 different time signatures (in this  
case 4/4, 2/2 and 3/4 why is it when I set my showLastLength as R1  
rather R2. do I get the crash? and only when using \score AND  
\compressfullbarrests - either one on their own doesn't have a problem.

Ultimately I can live with using R2. but that's just a workaround and  
fundamentally we shouldn't be crashing.

I haven't tried this in Windows or Linux but have provided the crash  
dump from my Mac.
