%{ warning message: programming error: minimise_least_squares (): Nothing to minimise This means that vertical spacing is triggered before line breaking %}

\version "2.11.23" \paper{ragged-right=##t}

{ c'8 e' g' c''\laissezVibrer r2 | c'8 e' g' c'' r2 }

This error message is printed from lily/least-square.cc

Here's another example that produces this warning; the dotted rhythms are necessary to produce this warning, as is the changing pitch in the eighth notes:

\version "2.11.23" \paper{ ragged-right=##t } << { e''2 ~ e''8 e''8 g'' g''} \ { e2 ~ e8 r4. } >>

Perhaps it has something to do with calculating the angle of beams?

These are 2 separate bugs, actually.

fixed the 2nd too
