The error (with debugging details) can be reproduced by running eval-expression (ESC :), then entering the problematic code from mmm-auto.el:

(if (not (string-match "XEmacs" (emacs-version)))
    (define-obsolete-function-alias 'mmm-add-find-file-hooks 'mmm-add-find-file-hook
      "0.3.8"
      "Both `mmm-add-find-file-hooks' and `mmm-add-find-file-hook' are deprecated.")
  (define-obsolete-function-alias 'mmm-add-find-file-hooks 'mmm-add-find-file-hook))

This seems to be due to the fact that define-obsolete-function-alias is a macro, which is expanded when the file is loaded, i.e. both macros are expanded.

This is reproducible with GNU Emacs 28.2 and 29.1, but not with 27.1. However, it seems that this was working before GNU Emacs 28 for this reason.

My emacs version GNU Emacs 29.1 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.38, cairo version 1.16.0) of 2023-08-30, modified by Debian

What should I do to fix it then?

What should I do to fix it then?

An easy solution could be to drop XEmacs support (or ask XEmacs to implement the when feature), i.e. to change the above code to just:

(define-obsolete-function-alias 'mmm-add-find-file-hooks 'mmm-add-find-file-hook
  "0.3.8"
  "Both `mmm-add-find-file-hooks' and `mmm-add-find-file-hook' are deprecated.")

Thx a ton...

[dgutov]

@vinc17fr Thank you for the help, but apparently the code you are quoting was added (or at least augmented) by the Debian packager, to try to keep the XEmacs support alive.

[dgutov]

I guess we might as well remove them in the next version, to make it easier for the packager. Both functions have been non-recommended for 20+ years now.
