No problem here, though I'm using latest git master which includes
recent changes to the markup code (not least that there's no
define-builtin-markup-command any more).

It's a helper function in define-markup-commands.scm used by the
markup-list commands:
(if (ly:music-output? output)
(space-lines baseline-skip
(map paper-system-stencil
(vector->list
(ly:paper-score-paper-systems output))))
