System Information
Operating system: Linux / Fedora 36
Graphics card: Intel® HD Graphics 3000 (SNB GT2), Thinkpad T520 onboard. Yes, ancient.

Blender Version
Broken: blender-3.2.0, blender-3.2.1 both from tarballs from download.blender.org
Worked: blender-3.1.2
Any attempt to create or load a grease pencil object results in instant crash.

Exact steps for others to reproduce the error
Start either blender 3.2.0 or 3.2.1. Settings don't appear to matter but just to be sure I did reset them to factory default. Then add add a grease pencil object, for example by hitting -a, Add->Grease Pencil->Empty. For me this results in an instant crash. Alternatively load a blend file containing a grease pencil object which also will result in instant crash.

Here are crash message and blender.crash.txt:

I guess I must be hitting some odd special case due to my ancient hw but until I can replace this ancient Thinkpad T520 I'd not mind if blender was working ;-)

Graphics card: Intel® HD Graphics 3000

Thanks for the report. Your GPU is below minimum requirements to run blender
This GPU model has Sandy Bridge architecture, which is quite old. To run newer version of blender [Haswell architecture and newer ]] are required. Also [ https:*en.wikipedia.org/wiki/List_of_Intel_graphics_processing_units#:~:text=Xeon%20E3%2D1260L-,HD%20Graphics%203000,-Mobile | see .
Installing the latest graphics driver sometimes helps to make such GPUs work, see here for more information. https://docs.blender.org/manual/en/dev/troubleshooting/gpu/index.html

If that doesn't help, use previous blender versions: https://download.blender.org/release/
