With the example file:
----------------------------------------------------------------------
* A
AAAA
*** B
BBBB
* C
CCCC
** D
DDDD
----------------------------------------------------------------------
If I hit "C-c C-e d" to convert this to PDF and view it, I see something like
1 A
AAAA
2 C
CCCC
2.1 D
DDDD
Neither the heading or text of section 'B' appears due to the incorrect
level of B (three stars rather than two). If I correct the level for B,
the heading and text appears.
I found this today when working on a document. It is my fault for
getting the level of heading B wrong, but is it possible to keep the
text in the pdf, or put a heading like '2.0.1 B'?

FYI: This is a know limitation of the LaTeX exporter[1] and the
current state of this issue (dealing with skipped levels) is that
patches for the problem are welcome. I agree that even if
skipped-level-headlines are not allowed, they shouldn't be silently
droped neither.
Best,

Thanks David, and apologies for not checking the archives. I'll put
bugfixing it my todo list!

I think I have a patch for this, see below. I've tested it briefly to
see that it works with both oddeven and odd level headings, but I would
appreciate other people taking a closer look/checking that it doesn't
break other things. I think I found the problem, in that if you have a
structure like
* A
*** B
(i.e. a level one and a level 3)
after it has found the level 1 content, it expects to find a level 2
subtree, whereas in fact there could be a level 2+ tree. See the
comment in the code for the change I made.
