Virtubox crashes when the vbox window was resized. Host Windows 10 Pro (64-bit), guest Debian GNU/Linux

Description
Host: Edition Windows 10 Pro (64-bit) version 21H1 Installed 2020/12/16 OS build 19043.1110 Experience Windows Feature Experience Pack 120.2212.3530.0
Guest: Debian GNU/Linux
When I try to resize the VBox window under Windows 10 Pro (64-bit) by grabbing the right edge and tried to shrink the width, VBox crashed.
It seems it encountered exception. Funny, I see screen count changed or something to that effect in the attached log. I only have a single physical display.
TIA

From the log, VBox seemed to think that the guest screen count changed. But no way, I have only a single physical display and my linux install is pretty much straight-forward.
I would rather suspect memory allocation issue. On line 2108, I see pvVRAM=0000000000000000 suggesting that the (newly allocated?) pvBRAM may be possibly assigned a null pointer due to memory stavation?
... somewhat old log lines are omitted ...
... Obviously, my attempt to resize VBox window resulted in the guest screen resize ...

Hello.
What is the Debian version and used desktop environment? It is relevant since guest desktop resizing uses different code paths on X11 and wayland desktops.
comment:6 by , 3 years ago
Debian version. Oops, I have updated the version since my report. Let me see. On August 1 when the bug was reported, and actually the crashing Vbox was started on July 30, according to the log line:
Log opened 2021-07-30T06:45:08.410085500Z
(from the log file attached in the original post).
I was using Debian GNU/linux kernel 5.10.0-7-amd64.

I am using xfce4.
Presumably it is X11 (?) based. Debian Wiki on Wayland states XFCE is unsupported.

Partial excerpt from "ps axg" output.

As for the VBox.log, isn't the VBox.log attached to the original post enough?

(I am afraid the logs have been rotated already and no other logs from July 30 are left behind.)

We are interested (among other things) the GA version installed during said bug was happening. It is always better to post the whole log (it is a few hundreds of kilobytes anyway) than playing the guessing game.
Log file when the crash happened.
