Subj : SEGV on aarch64

Hi DM,

I'm running synchronet on a CM5 under proxmox (its a LXC container), and I was looking to move it to a VM (QEMU).

When I created the VM and started sbbs, it SEGVs. (My sbbs was build a month or two ago...)

So I build a debug version with code (as of today) - and it still SEGVs, but now I have a backtrace.

Any ideas? The host is alpine linux, but the docker container is debian bullseye.
