Remember to cover the basics, that is, what you expected to happen and what in fact did happen. You don't know how to make a good report? See
http://orgmode.org/manual/Feedback.html#Feedback Your bug report will be posted to the Org-mode mailing list. ------------------------------------------------------------------------ With the following file: #+BEGIN_SRC org ,#+BEGIN_SRC sh :tangle "test.sh" ./test ,#+END_SRC ,* header #+END_SRC calling `org-babel-tangle` fails with stack trace: string-match("..." nil) org-store-link(nil) org-babel-tangle-single-block(1) org-babel-tangle-collect-blocks(nil nil) org-babel-tangle(nil) call-interactively(org-babel-tangle nil nil) The problem is fixable by adding a dummy heading that `org-babel-tangle` can give an ID to. (Note my `org-id-link-to-org-use-id` is set to `t`.) I'm unsure on what correct behavior here would be; it seems the variable must be honored in any case, so perhaps it would be best to give a better error message along the lines of 'cannot give identification to a null heading' or somesuch.
