thanks for this solution!

In my real-life example, I got

lilypond: ../flower/include/drul-array.hh:35: T& 
Drul_array<T>::at(Direction) [with T = scm_unused_struct*]: Zusicherung 
>>d == 1 || d == -1<< nicht erf?llt.
Aborted (core dumped)

but changing before-line-breaking to after-line-breaking did the trick.

I do not fully understand why, but it works.

Thanks,

Marc
