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
