Greetings,

There is a Stack overflow when exporting org file to pdf via latex.

So, I have a file ~/org/master.org which is 2885 lines long. After
exporting the whole file to pdf, and then exporting only one its subtree to
pdf as well, there is a stack overflow.

These are the steps to reproduce it:

1. C-c C-e p (that is, export the file to pdf via latex)
2. move to the subtree
3. C-c C-e 1 p (that is, export the subtree to pdf via latex)

Here is what I expect:

1. the master.pdf file with 102 pages
2. after exporting the subtree, the master.pdf file with 3 pages only

This is what I get:

1. the master.pdf file with 102 pages
2. instead of an updated version of master.pdf after executing C-C C-e 1
p, I see this in the *Messages* buffer:

Export buffer: 
Export subtree: 
Mark set
Exporting to PDF...
Exporting to LaTeX...
predictive-schedule-auto-dict-update: Stack overflow in equal

Bellow is the information automatically extracted by the
org-submit-bug-report routine.


Cheers,
Marko Dimjašević
