Hi Eric, I think this is a bug because the comments in the code say that
the buffer local values should be preserved.

The org-export-before-processing-hook is called in ox.el in the
org-export-with-buffer-copy macro form (
http://orgmode.org/cgit.cgi/org-mode.git/tree/lisp/ox.el?id=1c923b9ae734304b0dc6688ee056864facb7c3b8#n3002
)
 and org-export-with-buffer-copy macro docstring says:

Apply BODY in a copy of the current buffer.
The copy preserves local variables, visibility and contents of
the original buffer.  Point is at the beginning of the buffer
when BODY is applied.

So I was led to believe that the local variables will be preserved.. Or are
they lost at a later stage?

I'll dig into this and get back to you.

Thanks.
