Hi,

Here is a minimum working example:

=====
| abcd | efgh[fn:1] |
| ijkl | mnop[fn:1] |
| qrst | uvwx       |
| y    | z          |
* Footnotes

[fn:1] Some interesting footnote

=====

When I export it to PDF, this is the generated intermediate .tex file:

Notice that the second reference to the same footnote is some random
reference: \ref{org76fc583}

As a result, the second reference to the exact same footnote looks like
this (question marks: ??):

[image: pasted1]

Is there a fix for this? Or a workaround in org/latex?

Org-version: Org-mode version 8.3.5 (release_8.3.5-1061-g48a874 @

Thanks.
