Hello Org's developpers,
Some time ago I tried to export in html form an org file containing many
src blocks and ended with the following message :
org-html-do-format-code: Buffer is read-only: #<killed buffer>
After narrowing down my file here are the steps to reproduce :
emacs -q
(require 'htmlize) ;; this is important else `org-html-fontify-code`
;; will keep the wrong branch
;; open the ecm-org-src-ro.org ([1])
;; try to export as html
I've also attached a patch ([2]) to fix this.
I've also opened the bug 41641 with the sames informations.

When the type of src block involve an read-only buffer (ex:
compilation mode) avoid to setup the temp buffer as read-only and
error when processing it
* lisp/ox-html.el (org-html-fontify-code): set `inhibit-read-only' to
avoid read-only temp buffer.
