Blender Version
Broken: version: 3.2.0 Alpha, branch: master (modified), commit date: 2022-04-22 20:02, hash: 086938a306
Worked: (newest version of Blender that worked as expected)

(Sorry, I haven't been able to bisect it yet. I believe it worked until a couple of weeks ago. Note that the above commit hash is from UPBGE, but looks like it's reproducible for all regular Blender users on Arch-based Linux, as it can be seen here - https://github.com/bartoszek/AUR-blender-git/issues/10)

Short description of error

Recent build of Blender on Arch Linux crashes when using Cycles renderer with the following stacktrace:

Exact steps for others to reproduce the error

Launch Blender.
Switch to Cycles renderer.

Either render the scene or switch viewport shading mode to 'rendered'.

I just found that the official build doesn't show the same issue. Looks like it might have something to do with the fact that AUR packages are built against system libraries as is the convention with most Linux distros.

Hi, thanks for the report. We can only give support for official builds from blender.org though.

I understand why Blender devs feel reluctant to support unofficial builds. But can't anyone at least give some pointer about where I should look to identify and fix the cause?

As I mentioned above, the preferred way of installing applications on Linux is doing so from a package repository which is similar to how Mac users install most stuff from the App Store.

As such, we have many Arch-based Linux users who have been using one of those Blender packages for a long time and it's possible that the issue might affect users of other distros.

It's not like we can just tell them to stop using distro packages and use an official build instead, especially when it's not a recommended way of installing applications on Linux in general (i.e. ignoring Linux directory layout, duplicating a large portion of system libraries, not registering a proper file type entry or launcher shortcut, and so on).

There's a chance this was fixed already with 41b3feea85c : https://lists.blender.org/pipermail/bf-blender-cvs/2022-April/172470.html

Official builds of Blender in Linux are not bleeding edge from latest git.
So this could affect the official builds of Blender in a couple of time too.
I guess this is an early warning bug report

Of course, this report was a fast shot. The AUR maintainer Bartus should have looked at it first and then open an upsteam bug report himself. Give him some time.

We can use older packages from the AUR helper cache. Packages from late March are still compatible with current system libraries on Arch Linux.

@deadpin Just recompiled, It's not fixed.

Yeah, I'm not urging this must be fixed ASAP or anything like that. It's just that I'm also a maintainer of another AUR package based on Blender (upbge-git) so I'd like to get updates from here so I can take appropriate measures if needed, rather than having the report dismissed as irrelevant to the Blender project.

By the way, I heard Bartus is helping the Ukrainian refugees in Poland now so it may take a while before he could look into the issue.

Hi Xavier, I didn't mean to dismiss your issue, but the policy of this tracker is that it's for official Blender versions only. I am tagging @brecht here though, maybe he has a clue.

Hi Thomas, I understand. Thanks for the heads up and I hope we'd be able to resolve the problem before it may affect a broader userbase.

I've just rebuilt and tested my package after the commit. I can confirm that the crash is no longer reproducible indeed. Thanks much for the quick fix! :)
