And all the bars are right, and yet the second line is cramped and runs off.
It seems that systems will not break where there
is a glissando across the bar line (in 2.18.2).
The break that occurs after bar 4 is the last bar
line that isn't spanned by a glissando: hence the
cramped nature of the second system, as no
further breaks are possible. In addition, your
articulation "decrescendo molto" is too long to
fit on the second system, even if there is (just)
room for the music. If you shorten this or stack
the words using \column, you will just see the
final bar line, though displaced into the margin
- or at least I do with my default settings. If
you drop one of the glissandi, you can see three sensibly spaced systems.
I trust this helps.
