the "faulty" macro

This bug was filed from the crash reporting server and is br-33ed96ed-3b13-48f2-93d2-e18c54fef244.
=========================================

I made a Basic macro to hide/unhide some texts selected by their style, and now running it frequently crash LibreOffice, but not always.

It works fine with LibreOffice 6.3.6

I attach the macro for the record.

(this crash was on a fresh parallel install of LibreOffice 7.1.1 - following instructions from https://wiki.documentfoundation.org/Installing_in_parallel, with just the macro copy/pasted.

And if you need context, I'm a teacher, and I use this macro to allow me to produce from a same document a student version and a (enhanced) teacher one.

A sample documents with fonts needed

I added a crashing document and the fonts used in the styles within it.

[Hugotrip (hugotrip)]

As I was looking for a sample document, I found out that it seems it's not the macro itself that makes Libreoffice 7 crashing, but the attribute hidden to the paragraph style 'Prof' : more precisely it's when I check this attribute that the crash occurs (you may need to scroll within the document, once the change is done to see the crash) :
Indeed, I have another style in my macro that doesn't crash at all, and I tried to open the sample document with the attribute hidden already given (done by using a 6.3.6 version of LibreOffice) to the style 'Prof' and it doesn't make LibreOffice 7 crash, neither then unhiding the style (but re hiding it will make a crash again)

Hello there,

I've just tried the daily build, and so far, it seems fixed to me (testing on two documents crashing otherwise)

So I thank you now :)
