Hello Jens, I'm afraid I cannot test your issue. I don't have the ability to switch emacs version yet.
What I can tell you is that org-9.4 is working fine on GNU Emacs 27.1, and on Emacs 28.0.50. Does anyone have problem on the official Debian 10 repo emacs 1:26.1+1-3.2+deb10u1? Hope this helps, Jeremie - Org mode version 9.4 (release_9.4-9-g41a3c3 @ /home/djj/src/org-mode/lisp/) - GNU Emacs 28.0.50 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.5, cairo version 1.16.0) of 2020-09-01 Jens Lechtenboerger <lech...@wi.uni-muenster.de> writes: > Hi there, > > if I open an Org file on > “GNU Emacs 24.5.1 (x86_64-pc-linux-gnu, GTK+ Version 3.22.11) of > 2017-09-12 on hullmann, modified by Debian” > I get this error (which I don’t know how to debug): > > Eager macro-expansion failure: (wrong-type-argument listp :pcase--succeed) > > Recipe: > touch empty.org > curl -L https://orgmode.org/elpa/org-plus-contrib-20200914.tar > org.tar > mkdir org && tar xf org.tar -C org --strip-components 1 > rm -f org.tar > emacs -Q -L org > C-x C-f empty.org > > In ORG-NEWS, I only found that “Emacs 24.4 or above is suggested.” > Did that change? > > Best wishes > Jens
