Virtual Machine crash while Copy text on Host

Post by aaarim »

Windows 10 + VirtualBox 6.1.14 + Ubuntu 20.04 + Guest Additions 6.1.14

Sometimes (one tome per day) I have virtual machine crash while copy simple text from browser (few words).
Can not reproduce it specially.

PS: Did not notice such behavior for 6.1.10 and older. Only for 6.1.12 and 6.1.14

Does the same thing happen when copying from a text editor document? What browser? Can you make the same text from the same website in the browser crash the guest each time?

If you can reproduce the crash, does the same crash happen if you then uninstall 6.1.12/14 and reinstall 6.1.10?

We'd need a reproducible pattern of events to set up a good test for the devs.

It's hard reproduce. May be just open virtual machine with activated clipboard buffer and do casual working things.

Screenshot in attachment. Simple selection "git ls-tree --full-tree -r --name-only HEA" and copy from Firefox and Virtualbox crash in background...
Can not reproduce with this simple example... I think need more complex test with previous states. But I do not remember previous clipboard content.

I will try to found reproducible test...

Version 6.1.18
Guest Additions: Fixed a VM segfault on copy with shared clipboard with X11 (bug #19226)
Looks similar.

We will still need a reproducible test.

During installation of the VirtualBox Guest Additions 6.1.24 (GA), building the VirtualBox kernel module vboxguest failed, so that the pre-installed Ubuntu version 6.1.16_Ubuntu gets used. Please re-install the GA and especially pay attention to error messages.

Strange... Checked updates, reinstall guest additions, checked building output, checked modinfo output, checked logs... And now it's 6.1.24 exactly.
But I think that 19165 - it's fix on host side and no matter guest additions versions. Anyway - same versions Virtualbox and guest additions is better.

It's hard reproducing crash. Just one word (it was IP address last time) and crash is here. Trying do same thing many times after - and no luck with crash.

Let see what happening now with new Guest Additions...

PS: Never see such bug before 6.1 version (for ten years).
