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

Thanks.
