Bug confirmed (but I didn't try all your workarounds, just the no spaces
before the #+begin_src and no space after the colon in the #+name).

I take it it was working on 7.4?

Nick

PS. One side note: the syntax of code blocks is

     #+NAME: <name>
     #+BEGIN_SRC <language> <switches> <header arguments>
       <body>
     #+END_SRC

so no emacs-lisp on the #+end_src line.
