I guess it's Windows only issue; clipboard handling is OS-specific.

Comment 3 is likely something different or related to bug 124647

Enable skia doesn't solve the issue.

Also with Ver 3.3
Aoo directly crash after open the file.

On pc Debian x86-64 with master sources updated today, I got an assertion.

I noticed that if I wait a bit more once the file is opened (I mean until there's no extra log in console), I don't get the assertion.
Comment 8 Stéphane Guillou (stragu) 2024-02-27 09:14:29 UTC 
No crash in:

Version: 24.8.0.0.alpha0+ (X86_64) / LibreOffice Community
Build ID: d2fa44db6f8a1badece63856ee0f12db4cba9b28
CPU threads: 8; OS: Linux 6.5; UI render: default; VCL: gtk3

However, crashed as described on Windows 11:

Version: 24.2.0.3 (X86_64) / LibreOffice Community

Crash report: https://crashreport.libreoffice.org/stats/crash_details/ddf410e0-0f9d-45a8-81a2-9e32f4f39844

As Telesto said, let's keep it Windows-specific.
Comment 9 Stéphane Guillou (stragu) 2024-02-28 12:11:23 UTC 
Also reproduced on 7.6.5.2 (win 11).

> As Telesto said, let's keep it Windows-specific.

I was able to repro with:

Version: 24.8.0.0.alpha0+ (X86_64) / LibreOffice Community
Build ID: 53c5d570cab036b23f4969b858a648c8f0c24f93
CPU threads: 8; OS: Linux 6.5; UI render: default; VCL: gtk3
Locale: en-US (C.UTF-8); UI: en-US
Calc: threaded

So, not OS-specific.  Not sure how to solve it either.  Interesting lines of output:

Comment 11 Stéphane Guillou (stragu) 2024-03-20 07:09:04 UTC 
It seems we can only crash it on Linux with a debug build (comment 3, comment 7, I assume comment 10 too, Matt?).

That's the case on my end, only crashes with debug build:

Version: 24.8.0.0.alpha0+ (X86_64) / LibreOffice Community

On Windows 11, no crash in 7.5.0.3 -> regression.

Yes, that's correct.

I bibisected this using win64-7.6 repo and got the following result:

bad commit is c804c5354855188b5a37219cfe11dc079dc235f4

    sw content control: fix lost properties on copy&paste

Comment 13 Miklos Vajna 2024-03-27 07:15:10 UTC 
I think what happens here (based on Julien's backtrace) is that we have an original document with char styles and we create a clipboard document, but the SwFormat instances in the clipboard document refer to char styles in the original document, so it's important the full SwDoc is only deleted once the clipboard document is deleted.

Normally the SwView has a weak reference to these clipboard documents, so these transferable instances are disposed/invalidated by the time the original SwDoc gets deleted, but not in this case, because we have some kind of leak.

It's not yet clear to me how the above commit changes anything in this mechanism, given that the failing assert is all around char styles and their usage, not around content control.
