Recent export bug?

[Thomas S. Dye <tsd@tsdye.com>]

Aloha all,

The following minimal example doesn't export the Second heading to  
html.  The problem seems to be the :export: tag on the First heading.   
If I remove the tag, then both the First and Second headings make it  
into the export.  I don't expect the :export: tag on the First heading  
to stop export of the Second heading.

I found this behavior when I tried unsuccessfully to export an org  
file that successfully exported last on April 6th.  I don't believe  
I've changed any html export settings in the meantime.

I tried to run git bisect, but if I go far enough back in time then I  
run up against this:
eval-buffer: Symbol's function definition is void: org-overlay-put

This leaves me way over my head, but I did want you to know that I  
worked a bit to isolate the problem and did my best to track it down  
without success.

All the best,
Tom
