[Orgmode] Fail to compile a file's LaTeX export

[Leo]

Hello,

While taking some common lisp notes, I found compiling the following org
file's LaTeX output fails.

--------------------------------
#+title: test file

* one
  1. (char "string" 2) => #\r
  2. define-modify-macro
  3. (code-char 66) => #\B and (char-code #\B) => 66
  4. terpri and fresh-line
  5. "~n&" print a new line if not at the beginning of a line and then n-1 new 
lines.
--------------------------------
