Hello Mark,
the issue here is not the break, but the spanner ending on a multimeasure
rest, which causes in the hairpin not having a right bound. The reason for
this is that the engraver for dynamics only listenes to note columns, which
includes notes and rests. It does not include MM rests.
This then causes the code to fail, as (ly:spanner-bound grob RIGHT) will
return '(). To fix this use
\override Hairpin.to-barline =
#(lambda (grob)
(let* ((right-bound (ly:spanner-bound grob RIGHT))
(nhds (and (ly:grob? right-bound) (ly:grob-object right-bound
'note-heads #f))))
(not nhds)))
This way if there is no right bound the behaviour will be just like as if
there was a rest.
You will by the way get the same problem when you end the Hairpin on a skip.
Cheers,
Valentin
