StackOverflow when parsing .prg file

[baramuse]

Describe the bug
Vsiaul studio crashes when editing a .prg file.
If I only open the file, it's ok, when I start editing after a short while it will crash

I've create a crashdump of VS when crashing and replayed it with VS, here is the screenshot when it happens.
I've also enabled and attached the X#logs for when it's crashing, looks like an infinite loop...

I think we already had that type of crash : #1416

Screenshots

Desktop (please complete the following information):

• OS: Window11
• Version 2.20.0.3 and also 2.21.0.4

Basile,
Can you also send me the source of the file "Methodes Publiques Locasyst.prg", or even better the whole project?
