\crossStaff plus Beam-positions clips low beam

[damianlegassick]

Hi all

reviving an old problem here...

https://code.google.com/archive/p/lilypond/issues/2849

If I compile the following with -dbackend=eps the beam is not visible

test.pdf
Description: Adobe PDF document

I’ve tried 2.19.39 as well, same problem

Eluze’s 2012 suggestion of adding \markup “ “ to the end of the file does make the beam visible, but adds too much whitespace below the image

any other ways to get round this? - I know I can crop the pdf externally, but I’d like the files cropped at the Lily stage as they change frequently. 

\header{ tagline = "" }

\version "2.18.2"

RH = { \crossStaff { <c''' e'''> } }

LH = { \clef bass \stemDown

  \override Beam #'positions = #'(-8 . -8)

  c,8[ \change Staff = "right" g'] }

\layout {

  \context { \StaffGroup \consists #Span_stem_engraver } 

}

\score {<<

  \new StaffGroup{<<

    \new Staff = "right" { \RH }

    \new Staff = "left" {\LH }

    >>}

>>}

thanks again
