I tried running convert-ly from HEAD, but it did not update the
references to ly:duration-length for some reason. Updating it by hand
fixed the problem in that script.
However, the following error is still happening. From what I can tell,
this is a separate problem from ly:duration-length; it has something to
do with midi generation but I can't seem to figure out what's triggering
it:
Parsing...ice-9/eval.scm:159:9: Throw to key `numerical-overflow' with args
`("divide" "Numerical overflow" #f #f)'.
Any hints as to where to start looking? As I said, it's a rather large
score and it'd be helpful to know where to start narrowing down the
problem.
