Itʼs worse than what you think: having an old version of org loaded
can cause miscompilation of a new version of org, even when using the
same version of Emacs. Itʼs probably down to macros. There was a
message to the org-mode list about it if youʼre interested in the
details (although I didnʼt save it).
