I tried it, and I'm sorry to say all the same problems keep happening.  

I tried the test you mentioned here:

https://lists.gnu.org/archive/html/emacs-orgmode/2024-03/msg00362.html

I loaded up my big Org file and moved around a while.  I got:

Function Name                              Call Count  Elapsed Time  Average Time
org-fold-core--property-symbol-get-create  33325       0.0058796690  1.764...e-07

I don't know if that's helpful.

For me all this is triggered by my work-diary.org file, which has fair bit of fontification in it: headings, 1200 clock entries, links, and so on.  It had a big clockable at the bottom, which gave me the "Stack overflow in regexp matcher" I mentioned last month:

https://lists.gnu.org/archive/html/emacs-orgmode/2024-02/msg00347.html

I moved the clocktable to another file and the error stopped.  But now it's back.  I've been adding to work-diary.org in the meantime, so perhaps the problem was triggered by going over some limit, and I got it down under that limit, but now it's back over.  Bruno's problem is triggered by a large file---but surely many people here have large files in Org, so why aren't they seeing this?  Frustrating.

I turned on debugging and will the regex overflow stack trace below in case it's helpful.  (This is beyond my debugging skills, so I'm just pasting in anything I've got now.)

To be clear:  all these problems happen when I use the latest Org development source.  Using the Org in the current Emacs development tree (I'm on 30.0.50), there's no problem.  The Emacs source doesn't have the commit I identified earlier as being where my problems started.  I'm toggling between versions by commenting this on or off:

(use-package org
    ;; :pin manual
    ;; :load-path "/usr/local/src/org-mode/lisp"

Ihor and Bruno, might it help if we did a video call and shared screens to see problems live?  My Lisp is limited but I'll help how I can.


Thanks,

Bill
