Bug ID: 150946
Summary: Random crashes while working on large documents,
forcing me to restart my PC
Product: LibreOffice
Version: 7.4.0.3 release
Hardware: x86-64 (AMD64)
OS: Windows (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: LibreOffice
Assignee: [email protected]
Reporter: [email protected]

ZIP file containing the document I was using, the bug reports, and the "fault
module" that is listed in the bug reports (note: the "fault module" only causes
errors in LibreOffice, not other programs)
OS: Windows 10 Home 21H2 OS Build 19044.1989 (also happened on OS build
19044.1989)
LibreOffice version: 7.4.0.3 (also happened on 7.3.5.2)
Note: I am not sure if this is a LibreOffice issue (since all of LibreOffice
crashes) or a Writer issue (since I have only seen it crash on Writer). I am
listing LibreOffice as the component since I don't know whether this bug exists
on Calc and Impress.
Issue: LibreOffice Writer hangs and crashes at random. This freezes almost
every application including the Windows user interface. However, the computer
doesn't show any signs of high CPU usage (like heating up or fans running) so
this is probably LibreOffice just being idle and interfering with other
programs.
How to reproduce: Happens at random (usually once in one/two days) while
working on larger documents like the one I am attaching named “Bug Demo” (the
text is gibberish because I used “Replace All” on individual letters to get rid
of the actual contents, but the layout is the same), but usually I do a lot of
the following so the issue may be caused by something I am doing that most
users don't do frequently like:
1. Cut-and-pasting lots of text
2. Scrolling back and forth frequently
3. Opening multiple windows for the same document for reference
4. Using extremely small font sizes
5. Leaving LibreOffice open in the background for a while without saving
The following programs are affected whenever LibreOffice crashes:
1. Windows Explorer (completely freezes until either my PC somehow recovers
or I do a forced shutdown. It handles the UI on Windows)
2. Windows Security (specifically the Ctrl+Alt+Del shortcut) (doesn’t
respond until my PC somehow recovers or I do a forced shutdown. Under normal
circumstances, it should always respond immediately and let me open Task
Manager to close LibreOffice)
3. Google Chrome and Microsoft Edge (both of them freeze on-screen output
until my PC somehow recovers or I do a forced shutdown, but continue playing
audio)
4. RealTek HD Audio Universal Service (continues working, but audio
crackles every time I try to type something on the keyboard when LibreOffice is
frozen. It handles all audio output on my PC)
