Inside org-babel code blocks, emacs matches parens incorrectly whenever different bracket types (eg <> {} []) are used.
For example the following in an .org file will cause check-parens to throw an error:
#+BEGIN_SRC emacs-lisp
(> 1 0)
#+END_SRC
Where in an .el it will interpret the parens correctly. This error also occurs with show-paren-mode and evil-jump-item.
