Joe, Ben,

I downloaded the attachment and likewise had no error on compiling it on Mac OS 
X 10.13.6.

Lilypond version: 2.21.0
Frescobaldi 2.20.0

Looking at this thread:

 
http://lilypond.1069038.n5.nabble.com/Strange-error-with-no-traceable-cause-td213613.html

suggests that there is a garbage-hunting fault in lilypond. This would fit in 
with your difficulty in creating a minimum working example.

I haven’t studied your file in depth but I notice that line 266 is an 
incomplete bar - would it help to pad it out with rests or spaces? 
I also notice that there is no bar 36 in the “pedal” variable. In general, 
Lilypond is very tolerant of such things, but they might make a difference here.
