Thanks for the info. I have tried this, but it doesn't appear to 
be helping.

I did a few tests with lilypond, and here is what I found. I have 
a test.scm file containing:

(display (* 999)) (newline)
(display (* 999 999)) (newline)
(display (* 999 999 999)) (newline)

lilypond.exe -e '(load \"test.scm\")' test.ly
GNU LilyPond 2.23.10 (running Guile 2.2)
999
998001
997002999

That is fine. Now, if I try compiling test.scm to test.go, I get:

lilypond.exe -e '(use-modules (system base compile))(compile-file 
\"test.scm\" #:output-file \"test.go\")' test.ly
GNU LilyPond 2.23.10 (running Guile 2.2)
ice-9/boot-9.scm:752:25: In procedure dispatch-exception:
In procedure bytevector-u64-set!: Value out of range: -149659645

That doesn't work, so I compile test.scm to test.go with guile on 
my Mac. If I then try loading the generated test.go with lilypond, 
I get:

lilypond.exe -e '(load \"test.go\")' test.ly
GNU LilyPond 2.23.10 (running Guile 2.2)
999
998001
-76738825

Now, it is possible that the problem is that I am trying to run a 
.go file compiled on macOS on a Windows machine, and that the two 
platforms are different enough that the .go file can't be reused. 
And because I get that "Value out of range" error when compiling 
on Windows, I am probably stuck with .scm files instead of 
compiled .go files.
