bug in org-element--object-lex seen when exporting (Invalid search bound, wrong side of point)

[Daniel Clemente]

Hi. I describe a rare bug seen in today's org-mode (8.3.6) running in emacs 26.0.50.1.

1. emacs -Q, and load org-mode
2. Use this file (two lines):

* <<<a>>>
a-bug

3. export to HTML  (C-c C-e h h)

I got:

Debugger entered--Lisp error: (error "Invalid search bound (wrong side of point)")

  org-element--parse-elements(2 19 first-section nil nil nil (org-data nil))
  org-element-parse-buffer(nil nil)
  …



It happens with one-letter radios. I found it because I had <<<R>>> and r-cran in the same file.

Greetings,

Daniel

I can reproduce it, and will fix it in a few hours.

Bastien, I consider this to be a blocking bug for 9.0 release, in case
your are planning to make the release very soon.

I will of course wait for your "go" and review the major changes
carefully before doing the release.
