The Org mode in the Org Git does not export

["Rudolf Adamkovič" <salutis@me.com>]

Hello smart people!

The Org mode from Git does not export my notebook, while the Org mode
that comes with Emacs 29 does.  Is that normal?  My 1.6 MB notebook
contains 2078 headings and lots of prose, mathematics, code, citations,
tables, ... virtually everything.

The minimal configuration used for testing:

| (setq-default org-use-extra-keys t)
| (setq org-export-use-babel nil ; <----------- NOTE no Babel execution
|       org-export-with-broken-links 'mark
|       org-cite-csl-styles-dir "~/"
|       org-cite-export-processors '((t csl)))
| (with-eval-after-load 'ox
|   (require 'oc-csl))

The Org mode in Emacs 29 (Emacs Git, e0565e3896) exports the notebook in
about 13 seconds, but the Org mode from Git (Org Git, ebbc2ffaa) keeps
exporting forever.  (FYI, the new Org announces that the buffer is
syntactically correct.)

When I attach the profiler before exporting and then abort with C-g, the
profiler reports that Org spends almost all of the time in
'org-export--generate-copy-script'.

P.S. A while ago, I tried to binary-search the problematic part in my
notebook, but I did not find it.  The export times got progressively
better as I cut the parts.  Worst-case, I can try this again.

Any ideas?
