xfce4-session segmentation faults after glib2 update

Hi. I am an Arch Linux user (on a very old Dell laptop), and since I updated the Arch glib2 package to 2.76.0-1 my xfce4-session crashes after a few minutes. There are no clear triggers, I do not need to put the system under any load for example. I posted details about my dumped cores to the Arch Linux forum: https://bbs.archlinux.org/viewtopic.php?id=284285

I already created an issue at the GNOME Gtilab: https://gitlab.gnome.org/GNOME/glib/-/issues/2941 – it was suggested there that I report to you instead. As I’m not a developer, I can only hope that one side or the other will be able to make sense of what is happening. Of course I’ll do my best to provide any further details you may need.
