Created attachment 856450 [details] emerge --info lvm2 I'm having this after doing a world rebuild (emerge -1ev @world). I haven't done any diagnostics aside from the backtrace in gdb. Rebuilding USE=-udev fixes the problem. # gdb /sbin/lvs GNU gdb (Gentoo 13.1 vanilla) 13.1 Copyright (C) 2023 Free Software Foundation, Inc.

Can you reproduce this with systemd-utils-252*? I'm inclined to not worry further until it's confirmed with >=sys-apps/systemd-252.7 or >=sys-apps/systemd-utils-252.7 because of the issues within systemd's buffer handling (or shenanigans) until those versions, which caused previous FPs with libudev.
(In reply to Sam James from comment #1) > Can you reproduce this with systemd-utils-252*? I added 252.7 to my package.accept and rebuilt lvm2 with USE=udev and it indeed works! > I'm inclined to not worry further until it's confirmed with > >=sys-apps/systemd-252.7 or >=sys-apps/systemd-utils-252.7 because of the > issues within systemd's buffer handling (or shenanigans) until those > versions, which caused previous FPs with libudev. I'm going to leave those terrors for another person to be exasperated over. I have to analyze enough bad code as it is. :) Thank you, Sam. So should 2.5.1 be removed from stable?
systemd-utils-252.7 was marked stable earlier today (bug 899946).
