Short description of error
After resizing a panel in the Sequencer/Preview menu on the Video Sequence Editor and playing the timeline, Blender crashes. The issue seems to not happen on Ubuntu 20.04 LTS, though.
Exact steps for others to reproduce the error

Can you update your GPU driver and check if this resolves the problem?
Just updated to latest version and the issue still remains.
Driver 391.35 for GT 630M on Windows 10 Home. Not an issue on Ubuntu 20.04 LTS, will check driver version there as well.

FWIW no crash on macOS 10.15.5 either

I suspect some openGL issue here not necessarily linked to VSE exclusively.
Can you run Blender from command line with -d argument? I gues it would be
blender -d
and paste here console output? I am not sure if it will contain stack trace in Linux, if not there will becrash.txt
file mentioned in the end please upload that as well.Here is the error I get on running Blender 2.83 with the -d flag on Windows 10 Home:
Here is the terminal on Linux (no crash):
Added subscriber: @ChristopherAnderssarian
Could you run the debug argument with 2.90.0, there should be a stack trace attached to that.
Ok!
Here is the terminal after running Blender 2.90.0 Alpha with today's build on Windows 10 Home:
And here is the crash info with the stack trace:
blender.crash.txt
Changed status from 'Needs User Info' to: 'Needs Developer To Reproduce'
Changed status from 'Needs Developer To Reproduce' to: 'Confirmed'
Thanks for crash file. I got confused and thought that crash was on linux.
I was able to reproduce now when running blender from command line, but I am still not able to reproduce from debugger. But that is all I need now.
I have been able to reproduce from within debugger, but only when I run with
-d
argument.So far I am not sure if this is bug in tool system in general or in VSE implementation.

Here is an ASAN output: P1482.
From the backtrace it seems that it might be something more generic than sequencer. @ideasman42, @JulianEisel, do you mind having a look here?

Thanks!!! Will this be ported to 2.83 as well? It seems to be a pretty straightforward and non code breaking patch.
