Reproduction with emacs -Q:
(with-current-buffer (get-buffer-create "*broken*")
(require 'cl-lib)
(erase-buffer)
(delete-all-overlays)
(fundamental-mode)
(insert "AAAAA")
(goto-char (point-min))
;; Add two faces
(set-text-properties (point-min) (point-max) '(face font-lock-type-face))
(let ((ov (make-overlay (point-min) (point-max))))
(overlay-put ov 'face 'font-lock-negation-char-face))
;; This passes, proving that font-lock-negation-char-face is not contributing
to the
;; foreground color
(cl-assert (eq (face-attribute 'font-lock-negation-char-face :foreground)
'unspecified))
;; This fails: foreground-color-at-point reads the face of the overlay, sees
that it's undefined,
;; and ignores the 'face text property
(cl-assert (eq (foreground-color-at-point)
(face-attribute 'font-lock-type-face :foreground)))
(pop-to-buffer (current-buffer)))
Let me know if I can provide more info.
