Hi,
Here's a minimal document:
----BEGIN EXAMPLE----
#+title: Testing
* Src blocks
Here's some Lisp:
#+begin_src emacs-lisp
(message "Hello world!")
#+end_src
----END EXAMPLE----
When I try to export the "Src blocks" subtree to PDF via LaTeX, I get
the error:
"unbalanced begin/end_src blocks"
Export of the whole document to PDF via LaTeX is not affected.
Neither, initially, is HTML export, including subtree export to HTML.
However, after getting an error by trying to export the subtree to
LaTeX, I get the same error when trying to export to HTML (whether
subtree or the whole document). I can "clear" the HTML export error by
exporting the whole document via LaTeX again.
I'm using Org 7.7 (pulled this morning) on GNU Emacs 23.3.1 on a Mac.
Yours,
Christian

I have the same problem.
It occurs on a 2nd pass through org-export-blocks-preprocess (in
org-exp-blocks.el).
1st pass runs OK, 2nd pass gets the error condition.
1st pass processes the following:
(buffer-substring match-start (point-max)) ->
"#+begin_src emacs-lisp\n (message \"Hello, World!\")\n#+end_src\n"
2nd pass processes an emptied skeleton of the block
(buffer-substring match-start (point-max)) ->
"#+begin_src emacs-lisp\n#+end_src\n"
And fails to balance begin with end.
At this point in the code, the regular expression for matching
begin/end contains (I made ^M and tab visible here):
inner-re = "[\r\n][\t ]*#\\+\\(begin\\|end\\)_src"
And this expression fails right away:
(re-search-forward inner-re nil t) -> nil
I'll try to dig further into what's goning on.
Regards,
.j.
