Xorg 21.1.10-1 crashes after update to (lib32-)mesa 1:23.3.2-1

Description:

My Xorg server segfaults on start/login after today's mesa update

Additional info:

Did an update of these two packages today (from /var/log/pacman.log):

[2023-12-31T19:21:25+0100] [ALPM] upgraded mesa (1:23.3.1-1 -> 1:23.3.2-1)
[2023-12-31T19:21:25+0100] [ALPM] upgraded lib32-mesa (1:23.3.1-1 -> 1:23.3.2-1)

After the update and a reboot, observed my Xorg constantly crashing on start: Xorg.0.log.old

Downgrading these two packages to their previous versions helped me start Xorg successfully:

[2023-12-31T19:56:55+0100] [ALPM] downgraded mesa (1:23.3.2-1 -> 1:23.3.1-1)
[2023-12-31T19:56:55+0100] [ALPM] downgraded lib32-mesa (1:23.3.2-1 -> 1:23.3.1-1)

I suspect that my GPU might be part of the problem: it is a relatively old Nvidia GTX 1070:
