Issue with deep-copy/map-some-music a tuplet |

Hello,
I just noticed an inconsistent behavior with 2.25.0. The snippet below
doesn't compile; I don't know if there is a hidden problem inside it, but
it worked for all the versions prior to 2.25:
%-------------------------------------------------------------------
test = #(define-music-function (parser location music) (ly:music?)
(let
((musiccpy '()))
(begin
(set! musiccpy (ly:music-deep-copy music))
(map-some-music (lambda (evt)
(let ((nameUp (ly:music-property evt 'name)))
(cond
((eq? nameUp 'NoteEvent)
(set! evt '())
evt)
(else #f))
))
musiccpy)
)
#{ $musiccpy #}))
{
\test { \tuplet 3/2 { e'8 s s } }
}
%-------------------------------------------------------------------
Some observations:
1) the snippet compiles if the tuplet is removed
2) the snippet compiles if map-some-music is don on $music, instead of
$musiccpy
I don't know if it's a bug, but in any case, is there a way/workaround to
fix it while preserving both ly:music-deep-copy and the tuplet?
Thanks and Merry Christmas!
Paolo
