Lisp error during org export

[theldoria]

If I try to export an org source code block with literate-calc-mode and I happen to have a variable in it, I get an lisp error during htmlization.

For example, if I export this org file

#+begin_src literate-calc
Pi = 3.14159
#+end_src

I get:

Lisp error: (args-out-of-range "Pi " 0 12)

Btw. I was able to workaround this by setting literate-calc-font-lock-defaults to nil:

# -*- literate-calc-font-lock-defaults: nil -*-
#+begin_src literate-calc
Pi = 3.14159
#+end_src

Just realized I actually had to set literate-calc-font-lock-defaults globally to nil.

I had a quick look at this. This is exclusive to HTML export with htmlize for source code fontification (otherwise it just skips that). From skimming the source it seems that it's trying to splice in the overlays.[1] As such, I believe this to be an htmlize bug. [1]: https://github.com/hniksic/emacs-htmlize/blob/master/htmlize.el#L627
