Description
This seems to affect Intel GPUs prior to Generation 10 from what I'm reading. The original poster in blfs-dev has a Generation 9 GPU (UHD 600), on a Gemini Lake Celeron. I should be able to reproduce this on a Generation 9.5 GPU in theory (UHD 620).
It appears to be due to a commit in Mesa. The commit in question is https://gitlab.freedesktop.org/mesa/mesa/-/commit/19c57ea3bf6d77cf6f07f2a56e781f55b0e6013b, and the upstream bug report (which can be found at https://gitlab.freedesktop.org/mesa/mesa/-/issues/8542) hasn't had any activity for three months.
The user in the bug report above had HD Graphics 520, which is a Skylake GPU.
The post to blfs-dev can be found at https://lists.linuxfromscratch.org/sympa/arc/blfs-dev/2023-06/msg00043.html
Since this is a segmentation fault I'll take this and try to reproduce it. It also seems to affect GNOME only, and only in X11 mode. We'll probably need to add an optional patch into the book for Intel GPU users.

Reverting the commit allows to fix the issue on Haswell. patch added to the patch repo at e402797c.

Leaving the book update to Doug since he has taken the ticket, but just tell me if you want me to do it.

I've left a ping in the upstream ticket.
Meanwhile I guess we should recommend to use Wayland session (instead of X Org) for GNOME. And I'm not sure if the root cause of the issue is in xserver or xf86-video-intel, if the latter is the case we should discourage (or maybe archive) it.

Replying to pierre:

I'd say go for it :)
I can't reproduce it on UHD 620, but can on HD 4600. That system will need quite a bit of updates to be able to test the fix, but should be doable. My focus is going to be on other tickets for prioritization purposes, but I'll chip away at updating that system tomorrow as I'm waiting on other things.
