Re: Manual page breaking causing assertion failure

[Chris Yate]

So, it turns out this was easy to minimise the code. File is attached. It's
still ~70 bars but only one voice, which is the dynamics staff of a piano
score (without anything else), so it's only silent music.

"AutoPageBreaksOff" in the score block causes the exception failure.

I note some "insane spring distance" warnings.These don't happen in the
real thing.
