FWIW, I agree with Eric (modulo any bugs that might exist of course) - otherwise babel loses much of its appeal for literate programming. There are a couple of questions that need to be answered however: o why is the code block evaluated during export in Paul's case? That may be a result of Paul's config or a bug in babel - in either case, that should be easy to fix and Eric addressed that. o why did Paul's emacs session crash? That might be an emacs bug that will need to be addressed. Even if Paul's elisp code is completely broken, *it should not crash emacs*. Paul, can you post the code? Actually, the whole org file if that's possible, as well as emacs and org version? Thanks, Nick
