Short description of error
[Please fill out a short description of the error here]
Export a multimaterial plane to gltf 2.0 causes the Blender shut down.

Exact steps for others to reproduce the error
[Please describe the exact steps needed to reproduce the issue]
[Based on the default startup or an attached .blend file (as simple as possible)]


For version 2.91 and 2.92.0 Alpha. I created a multifaced plane with simple 2 face materials. When I try export to (factory build in) gltf 2.0 the Blender shut down.

I can't reproduce a crash with the provided file in Blender 2.91.0 or 2.92.0 (rBd11a87b88c4d) on Linux.

Could you please open Blender's installation directory and double click on the blender_debug_log.cmd? This will start Blender in debug mode and create log files. Try to make Blender crash again. Once it crashes the Windows Explorer should open and show you up to two files, a debug log and the system information. Add them to your bug report by clicking on the upload button as shown in the screenshot below or via drag and drop. Please also upload the crash log located in C:\Users\[your username]\AppData\Local\Temp\[project name].crash.txt (or simply type %TEMP% into the path bar of the Windows Explorer).

This could be the same issue as reported in T83685.

I use Ubuntu (Linux). I created debug file from console (./blender --debug --debug-cycles > blender_debug_output.txt 2>&1). The console made the file, but said also 'Aborted (memory dump)'. I have the same with Blender 2.83, so I guess this could be my Linux problem, console shows some deficiencies after major update of my Ubuntu. Thank you for help!

My bad I provided the instructions for Windows, but the command line flags from the batch script are the same for Linux so you've done everything right. Is the content you've copy and pasted the entire log file? It seems that you've also tried to attach the file, but restricted the visibility. Could you please change the policy back to the default?

Please check if Blender was able to write a crash log (.crash.txt) to /tmp and attach the file as well, should it exist.

Unfortunately none crash file in /tmp

Here is debug steps from Blender opened in debug all mode console, not all but form open the file:

Could you please check if running the operator from the Python console in Blender has the same effect (see T83685)?

I am using a portable version of Blender. If you could describe what exactly I should write to the console when I open it from the Blender folder I would be grateful.
From what I observed, simply exporting the start page (so with a box mesh) makes Blender disappear without any errors. I suppose these are some deficiencies of my Ubuntu. I'd like to reinstall Ubuntu from scratch, but currently I can't.

@Tomasz Biernacki (tombier) Do you also get a crash when you are enabling add-ons such as Extra Objects or A.N.T.Landscape?

Yes exactly. I tried check Add-ns "Add Mesh: A.N.T.Landscape" option in Blender Preferences and program crashed. "Extra Objects" the same effect.
