thank you for your update :)
on -current I still can't run it (didn't try on 6.6 as a client). with
ktrace I found it was producing a .core file in /var/crash which may
help finding what the issue is.
here is my client config
[general]
statuscommand = "/etc/mlvpn/mlvpn_updown.sh"
loglevel = 5
mode = "client"
mtu = 1442
tuntap = "tun"
interface_name = "tun0"
timeout = 30
password = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
cleartext_data = 0
[iwm0]
bindhost = "0.0.0.0"
remotehost = "XXXXXXXXXXXXXXX"
remoteport = 5081
bindfib = 1
[em0]
bindhost = "192.168.1.9"
remotehost = "XXXXXXXXXXXXXXX"
remoteport = 5080
bindfib = 0
When I run it
solene# mlvpn -c mlvpn.conf --debug -vvvvv -u _mlvpn

I installed debug-mlvpn and devel-libev but the egdb output is still ??, I'm
stuck here, I don't understand how to get informations from egdb :/
