Odd. Though the commit number is indeed correct.

Thanks! I was able to follow your steps this time.

Sigh... Should be fixed now. I did not expect that arguments to cache
functions could ever be markers.

After the fix, I was able to see the warning you were talking about in
the earlier email. Your test case revealed an important omission in the
cache logic when a huge number of edits are stacked together into
asynchronous cache queue. Thanks you for providing the excellent
reproducer!

On latest main, your example file is exported without any warnings.

Also, I noticed that the large number of edits makes the cache use a lot
of memory adding load onto the Emacs garbage collector. May I know what
exactly ox-hugo does that triggers that many edits? Exporting your
example files took approximately 30sec on my system (both with and
without cache). I believe that the speed can be improved if cache is
used more optimally.

Thanks! Fixed.
