I figured out the source of the problem:


*### header 1*

*<div class="foobar">*


*Lorem ipsum dolor sit amet...*

*### header 2*



*Lorem ipsum dolor sit amet...*
*</div>*

I had put that DIV in there for CSS reasons. So it's easy to 
fix/workaround: either put the DIV around both headers, or only around the 
body text below the headers.

However, I *think* the HTML that pandoc emits for the file (even with the 
weird TOC) is still valid (I checked it on validator.w3.org), and it seems 
odd that it would have this effect on the TOC, so maybe worth investigating 
further.
