This started out a few days ago in lilypond-user, where I sent it not
knowing if a bug was causing it or not. More tests indicate it
probably is.
---
Two-pass vertical spacing seems to be crashing with sufficiently
large scores AND forcing line breaks. For example, the output below
is pass one of the two-pass vertical spacing process. Note that if I
just run it without the first pass in lilypond there are no crashes.
Thanks, I'll look into this. Note, though, that the latest development versions will stretch the systems without needing a second pass. Two-pass spacing will therefore be phased out at some point in the future.

The code below is enough to do it. It's not meant to run straight
from the e-mail, as there are too many instruments to include.
However, I've trimmed it down to the minimum # of instruments needed
and removed any excess content. That is, take out \spacing and it
works. Take out the two-pass process and it works (duh).
