This bug (and bug#37824, which is the same) isn't due to the addition of the :extend attribute per se, but to that addition increasing the length of lface_attribute_index, which makes it necessary to adjust the length of internal-lisp-face-attributes, only the indices of which face-remap.el actually uses, as I noted above. Indeed, the following patch also fixes this bug: diff --git a/lisp/face-remap.el b/lisp/face-remap.el index 5cdecb92ee..e429752df9 100644 --- a/lisp/face-remap.el +++ b/lisp/face-remap.el @@ -66,7 +66,7 @@ ;; definitions are available. ;; (defvar internal-lisp-face-attributes - [nil + [nil nil :family :foundry :swidth :height :weight :slant :underline :inverse :foreground :background :stipple :overline :strike :box :font :inherit :fontset :vector]) But then we might as well just use a vector with all nil (or arbitrary) elements whose length is LFACE_VECTOR_SIZE (maybe that's even how the comment in face-remap.el quoted above could be understood). The simplest fix is to just add the missing attributes, as my first patch does, but then on any future changes to lface_vector_size internal-lisp-face-attributes will have to be correspondingly adjusted.

The proper fix must be to declare the vector in the C side using the real symbols like: Lisp_Object internal-lisp-face-attributes[LFACE_VECTOR_SIZE] = { Qnil QCfamily, QCfoundry, QCwidth QCheight, QCweight, QCslant, QCunderline, QCinverse_video, QCforeground, QCbackground, QCstipple, QCoverline, QCstrike_through, QCbox, QCfont, QCinherit, QCfontset, QCdistant_foreground, QCextend }; But using makevector or a similar api from C. This vector can be used in some other parts in the code where we are duplicating code now, but this will require a refactor I don't know if it is desired. So I will submit the simplest fix now and if Eli gives me a green light I will implement the better version. ^ permalink raw reply [flat|nested] 9+ messages in thread

Yes, and face-remap.el even says so. You can "steal" the way this is done from coding.c, starting around line 11635 (but there should be no need to staticpro a variable that is visible from Lisp, unlike Vcoding_category_table).
