I got nerd sniped into reducing this one for you :smile:

I think it's a markdown issue that might need resolved upstream, of course maybe it's appropriate to just abort highlighting in sx when there is an error since markdown-mode may never be perfect.

Reduced the size of the reproducer quite a lot by trial and error:

Or perhaps this is more useful.

Open a buffer with the name *test-sx-bug* and then execute:

(with-current-buffer "*test-sx-bug*" 
(erase-buffer)
(sx-question-mode--insert-markdown "**\n```\nfoo\n\n```")))

The last invocation of buffer-substring here doesn't include the ending ``` and I thin that's what causes the regex not to match. It runs against string:

Result: #("** ``` foo" 3 6 (markdown-gfm-block-begin (4 7 4 7 7 7 nil nil nil nil 7 7 #<buffer *test-sx-bug*>) face (markdown-markup-face . #1=(markdown-code-face)) invisible markdown-markup) 6 7 (invisible markdown-markup face #1# font-lock-multiline t) 7 10 (markdown-gfm-code (8 13) font-lock-multiline t face (markdown-pre-face . #1#)))

Inside of sx-question-mode--process-markdown-in-region function sx-question-mode--dont-fill-here errors out, specificaly when sx-question-mode--skip-and-fontify-pre gets called on a blank line in:

** ``` foo

\```

Remove the \\, it's there because I couldn't figure out escaping.

So sx-question-mode--skip-and-fontify-pre needs to not throw an error maybe? Not sure.

This seems to resolve the issue:

  "If there's a pre block ahead, handle it, skip it and return t.
Handling means to turn it into a button and remove erroneous
font-locking.

If DONT-FONTIFY is non-nil, just return the result and possibly
move point, don't create the code-block button."
  (let ((beg (line-beginning-position)))
    ;; To identify code-blocks we need to be at start of line.
    (goto-char beg)
    (when (fboundp 'markdown-syntax-propertize)
-      (markdown-syntax-propertize (point) (point-max)))
+      (ignore-errors
+      (markdown-syntax-propertize (point) (point-max))))
    (when (markdown-match-pre-blocks (line-end-position))
      (unless dont-fontify
        (sx-babel--make-pre-button beg (point)))
      t)))

I think it's correct because sx-question-mode--dont-fill-here expects the functions it calls in a list like sx-question-mode--skip-and-fontify-pre to not throw errors.

Thanks for the bug report and investigation! This project is definitely in maintenance mode for me – at least for the time being. If you were to open a PR with this change (appropriately formatted with the aggressive-indent package), I would merge it.
