When I 'rm -rf ~/.emacs.d/eln-cache, and restart Emacs, markdown-toc-generate-toc works correctly, but will eventually break again once various things are compiled again (sooner than later on a fast machine!). I'm not sure why the deny list hack works with an empty eln-cache, but not after a 'rm ~/.emacs.d/eln-cache/*/markdown-toc*'. > I thought it was some imenu thing, maybe it doesn't get autoloaded properly? Based on your hunch, I tested removing each rdep from the eln-cache, and I found that the (wrong-type-argument consp nil) bug occurs in markdown-mode-toc when markdown-mode is native compiled. markdown-toc-generate-toc succeeds for me when ~/.emacs.d/eln-cache/*/markdown-mode-*.eln and ~/.emacs.d/eln-cache/*/markdown-toc-*.eln and ~/.emacs.d/eln-cache/*/imenu-*.eln are removed, and emacs is started with this minimal workaround: emacs --eval="(setq native-comp-deferred-compilation-deny-list '(\"markdown-mode\"))" Yes, markdown-mode, no "toc". For this hack to work long-term for most users, it seems like imenu would probably need to be added to that list...but here's the strange thing: Logically, markdown-toc-generate-toc uses imenu, so it seems like it should trigger native-comp of imenu at L261. Neither markdown-mode, nor markdown-mode-toc explicitly (require 'imenu), so yes, I think you're right that one or both of them is depending on autoloads. Markdown-toc ends up native-compiled using this method, markdown-mode and imenu don't, and for reasons that aren't yet clear, this allows markdown-toc to function correctly. I also wonder if there may be a dash.el+native comp bug in play. 'hope this band-aid does the trick until the root of the problem can be identified. Nicholas
