My system was affected by the routing rule segfault on 236 but works
with 238. 237 already worked as well. I think it's safe to say
upstream has fixed it.

Could you test with v238 please and report back with your results.

Ok, thanks for the additional information, Rémi.
If you have a github account, it would be great if you can file an
upstream bug report at https://github.com/systemd/systemd/issues with
the information you provided here.

You might check https://github.com/systemd/systemd/issues/7708 before
doing that though, as it might be related.

Regards,
Michael

Your configuration seems to be incorrect. Please fix that and try again.

Please try to provide a backtrace of the crash.
For that, install the dbgsym packages for systemd and libsystemd0.

That kernel is not provided by Debian. Can you reproduce the issue with
a Debian kernel as well?
