I don't have `ob-conf', but this:

--8<---------------cut here---------------start------------->8---

#+begin_src emacs-lisp :exports both
   "Test

   ,* asterisk in src block"
#+end_src

--8<---------------cut here---------------end--------------->8---

shows the issue. Also, the #+[BEGIN|END]_SRC parts of the src block 
are showing up in the export.

Putting `org-escape-code-in-string' back in `org-babel-exp-code' here

:  ("body"  . ,(org-escape-code-in-string (nth 1 info)))

seems to fix this as long as there is a newline after the last #+END_SRC 
in the buffer.
