In the latest org release (9.0.5), I get errors when trying to save a buffer while editing inside a babel source block. I can reproduce this using Emacs 25.1 and 25.2rc2.

Using:

emacs -Q -l ~/org-debug.el

where org-debug.el just consists of (package-initialize) since I've previously installed org 9.0.5 using ELPA:

Open an org file,

Try to edit an org file:

#+BEGIN_SRC emacs-lisp
(+ 1 2)
#+END_SRC

Navigate inside the source block, press C-c '

Then try to save: C-x C-s

I get a fontification error at that point and the file does not save. If I use my whole config, this apparently snowballs into larger errors which sometimes cause Emacs to crash.
