Comment 2 Zbigniew Jędrzejewski-Szmek 2022-12-08 22:24:57 UTC
Fixed in systemd-252~rc3, 251.7. It's queued up for v250-stable (F36), but wasn't built yet.
Also maybe needs to be backported to v249-stable (F35).

But note that in those older versions we include much less stuff in the coredump message,
so it'd be much harder to hit this.
