coredumpctl coredumps on its own coredump :~-(

Please excuse this stupid question but "almighty google" has problems to find links to sentences with recurrent structure.

My systeminfo is:

Linux GarAus 3.17.4-1-ARCH #1 SMP PREEMPT Fri Nov 21 21:14:42 CET 2014 x86_64 GNU/Linux

and my systemd folder looks actually like this:

[134] yousry@GarAus> ls -lt /var/lib/systemd/coredump

if I try to debug the last coredump with

coredumpctl gdb

I get an ugly stack smashing:

zsh: abort (core dumped)  coredumpctl gdb

Of curse the real reason is the crash of another small application. I'm using the default config of coredumpctl:

[134] yousry@GarAus> cat /etc/systemd/coredump.conf

Any help would be greatly appreciated!

I too am experiencing this problem. Additionally, I am also observing crashes in Firefox and Thunderbird.

OK, it looks like the systemd-217-7 is broken. Downgrading to systemd-216 helped.

Seems unlikely given what changes went into 217-7.

A backtrace would be useful. debug symbols can be grabbed from my repo

hmm... I've experienced that as well, and from what I could tell it's related to lz4, specifically downgrading to lz4-123 fixed it for me. See https://bugs.archlinux.org/task/42944

Oh, that's what I've been looking for! Need to write that down. But there doesn't seem to be anything systemd-217-7 there, only up to 217-6?

Sigh. I guess I forgot to push those debug packages for -7. Some day debug packages in the official repos will be a real thing...

Thank you very much. With the latest update everything works just fine.
