I tried in a small LP - script to locate an error

\version "2.18.2"

#(define-public GES     37291/100003)
#(define-public G        8798/100003)

pitch-names =
  #`(
      (ges  . ,(ly:make-pitch -1 4 (- GES)))
      (g    . ,(ly:make-pitch -1 4    G))
    ) 

pitchGlyphs =
  #`(
      (-37291/100003 . "accidentals.flat")              ; Gb
      (  8798/100003 . "")                              ; G
    )
 
accidentalGlyphs =
  #`(
     (-37291/100003 . "accidentals.natural")    ; Gb
     (  8798/100003 . "accidentals.natural")    ; G
    )          
 
\layout {
  \context {
    \Score
    \override Accidental.glyph-name-alist           = \pitchGlyphs
    \override AccidentalCautionary.glyph-name-alist = \accidentalGlyphs
}}

#(ly:parser-set-note-names parser pitch-names)

\score {
     \new Voice {\time 2/2 ges'2 g'| ges'2 g'! | ges'2 g'? }
     \layout {}
     \midi {}   
}

this renders to

As you can see , it is missing in the first two measures the sign in front
of the G's ; in the third beat is shown a not quite correct sign.
However, the MIDI output plays the audio properly .

thank you
