When Org-mode buffer like this:

#+BEGIN_SRC clojure
(ns my.kk
  (:require '[incanter.core :as kk]))
#+END_SRC

#+BEGIN_SRC clojure
(print "hi")
(def kkkk "hello")
#+END_SRC

#+RESULTS:

When I have `(ns ..)` namespace clojure code in buffer, the second `(print
..)` clojure result nothing. But when I remove the first src block, the
`(print ..)` clojure src block works fine.

I'm using Org-mode version from `master` with `use-package` like this:

(use-package org
  :load-path "~/Code/Emacs/org-mode/lisp/"
  :pin manual
  :mode (("\\.org$" . org-mode))
  :config
  (use-package org-plus-contrib
    :load-path "~/Code/Emacs/org-mode/contrib/lisp/"
    :pin manual)
  )
