MAC: Crashes when openning a file/section via the TOC

[d3vf1x]

From time to time the textstudio app will crash wehn navigating to a section via the sidbar toc menu.
But it is only a specific section, all other will work fine.
Then after a while this section will also work again.
But once it crashes it will crash consistently, meaning after a restart of the application I can click the same section again and it will crash again.

Environment

TeXstudio 4.8.2 (git 4.8.2)
Using Qt Version 6.7.2, compiled with Qt 6.7.2 R

Crash report:
https://pastebin.com/r2300x3z

Expected behavior

Click on the Section should open the corresponding file and jump to the section in it

Actual behavior

Texstudio will crash. Even after restart the same error will show again.

a reproducible test case would be helpful...

[d3vf1x]

I cannot reproduce it reliably and i don't want to copy my whole project...
Any other idea?

[sunderme]

no way around a test case (or you can debug it yourself)
you can send larger test cases also directly to me (sunderme@gmx.de)

[d3vf1x]

I cannot find a minimal example that will "reliable" crash...
Is there another way to extract useful information for you?

[sunderme]

my guess is that the actual bug occurs way before the actual crash.
Are you closing documents before the crash happens ?

[d3vf1x]

No 100% sure but i would say no.
It is also consistent even after a restart of the program.
When I click on the same section again it will crash again.
But after some time and changes to some files I can click on the same section again and it will not crash...
Thats what it makes so hard to reproduce.
But most of the time i have about 18-12 tabs open.

[sunderme]

That I don't understand.
When you are at a state that it crashes after a restart when pressing on a certain section, it does not crash the next time ?

[d3vf1x]

Sorry for any confusion.

It will crash when I click on a particular entry of the Sidebar Window TOC.
Then after a restart I can click on the same Entry and it will crash again.
This can now be repeated indefinitely.

Sometimes it is only on entry that leads to a crash and sometimes there are multiple.

But it is never deterministic (as far as I understand) which entry will lead to a crash.

[sunderme]

And the crashing document(s) can't be used as a test case ? E.g. load these documents and press that section ?

[d3vf1x]

Its a work document i'm not allowed to share unfortunately.
I tried removing any relevant pages to be able to share it but every time I tried this after a crash, the bug will disappear.
It seems like altering the content of the pages will "fix" the bug tempoarly.

The funny thing is that I can open the relevant page (the page with the section that will cause the crash) manually without crashing.

[sunderme]

can you try do disable document caching (options/editor/cache document for faster reopening)

[d3vf1x]

I deactived it.
I will give it a try and report how it is going.

[d3vf1x]

No crashes since then.
This seems to be the "fix"

Thanks for your help
