I once created a function to show/print cues/quotes known to the parser.
Applied to the current use case:


%%%%%%%%%%%%%%%%%%%%%%%

\version "2.19.32"

cueNotes = \relative c'' {
   s4. <g d'>8 d' s4.
}

\addQuote "cueNotes" \cueNotes

#(define* (music-quotes-info #:optional (name "")(print #f))
 (let* ((music-quotes-list
          (hash-map->list cons (ly:parser-lookup 'musicQuotes)))
        (quote-vector (assoc-get name music-quotes-list #()))
        (quote-list (vector->list quote-vector)))
  (cond ((string-null? name)
         (display-scheme-music music-quotes-list))
        ((and (not (null? quote-list)) print)
         (make-sequential-music
           (map
             (lambda (m) (ly:prob-property (caadr m) 'music-cause))
             quote-list)))
        (else (display-scheme-music
                (make-sequential-music
                  (map
                    (lambda (m) (ly:prob-property (caadr m) 'music-cause))
                    quote-list)))))))

%% raw data of all quotes
%#(music-quotes-info)
%% `display-scheme-music'
#(music-quotes-info "cueNotes")
%% set `print' #t and use $ to get it printed
$(music-quotes-info "cueNotes" #t)

%%%%%%%%%%%%%%%%%%%%%%%

You'll see that only the chord's first note is quoted!
That's at least related to
NR
"
Known issues and warnings
Only the contents of the first Voice occurring in an \addQuote command
will be considered for quotation [...]
"

Though,
(1) It should not return a segfault
(2) The NR-warning talks about new Voices etc. Before testing I wasn't
aware that quoting chords is not supported as well. Should be
mentioned, imho
(3) I do understand why quoting more than a single voice is a problem,
but not how difficult it would be to support chords.


So I'm not sure whether it's a documentation issue or defect or an
enhancement or both.

Simon, I answered here on user-list to let Patrick Karl know, but
please add it on the tracker if you feel it might be helpful


Cheers,
