Stack overflow problem

[Valentin Villenave]

I just forgot to add (about the Stack Overflow thing) :

I'm running Lilypond 2.9.24 (but I had the same problem with 2.8 and
2.9.21) on a Slackware-based system.

Thank you for your cooperation ; I still think it's the best music
editing software in the world by the way :)
