Since commit 4751d0a66e97a61c763c150bb38f0446cc945f4d,
ly/ contains this:

#(set! standard-alteration-glyph-name-alist
         (append turkishMakamGlyphs

which changes the shared variable
standard-alteration-glyph-name-alist, used by the
\sharp markup command among others.


This means that if a snippet using
is compiled, in the same session, before a file
using \markup \sharp, the glyph changes.

Basically the mechanism should be changed so that
set! is no longer needed.
I think all that's needed is changing
     (define-public standard-alteration-glyph-name-alist
     (define-session-public standard-alteration-glyph-name-alist
and the session mechanism will take care to restore the initial value
after each file (as lang as you don't use destructive operations on
that initial value).

Indeed, thanks for reminding me. I'd prefer fixing
the mechanism, making the alist a layout variable
or something so it becomes customizable, but this
could be a good temporary fix.

Wouldn't it be better to _not_ reset
`standard-alteration-glyph-name-alist' at all?
The files, and all define some
custom-makam-glyph-alist and use this alist in \layout for
KeySignature, Accidental, AccidentalCautionary, TrillPitchAccidental,
Is this not sufficient? In other words why not simply delete all
occurrencies of:
#(set! standard-alteration-glyph-name-alist
        (append whateverMakamGlyphs
Then we would rely only on the mechanism partially demonstrated in

I'll test that later this WE

It's slightly more complicated. Chord names use the
alist directly (sigh):

(define-public (alteration->text-accidental-markup alteration)
    (if (short-glyph? alteration)
     ;; FIXME -- use current glyph-name-alist here.
     (assoc-get alteration standard-alteration-glyph-name-alist "")))))

and the markup commands \sharp et allies do the same.
