Hello,

I can confirm that systemd-networkd from the systemd 257.8-1~deb13u1 in
stable crashes on configurations with VLAN-aware bridges with a similar
stack trace to the one given in [0]. I have also seen this crash in one
of the Debian v258 RC's.

The problem seems to be that v257.8 is missing the fix in [1] that was
released in v257.9.
