Severity: grave
Justification: renders package unusable

Dear Maintainer,
I copied the example server file /usr/share/doc/vtun/examples/vtund-server.conf
into
/etc/vtund.conf and enabled server mode in /etc/default/vtun. When I start the
service
with systemctl I get the following error on the dmesg log:
[343358.769324] vtund[3002]: segfault at 0 ip 00005572cac05e34 sp
00007ffc9a47f610 error 4 in vtund[5572cabff000+b000] likely on CPU 0 (core 0,
socket 0)
[343358.769342] Code: 24 10 e8 2f 96 ff ff 85 c0 0f 88 0d 01 00 00 48 8b 44 24
10 48 89 44 24 08 48 85 c0 0f 84 f0 00 00 00 48 89 c3 90 48 8b 6b 18 <66> 44 39
7d 00 0f 85 d1 00 00 00 48 8b 73 08 4c 89 ef e8 55 97 ff
I checked the config and the manual but I haven't been able to use the package
due to the segfault.
BTW, the autogenerated systemd unit has the attributes RemainAfterExit=yes,
SuccessExitStatus=5 6,
so even on failure the unit appears as "active (exited)". Hence it needs a
"systemctl restart",
"systemctl start" won't do anything which is a bit counterintuitive.
Have a nice day.
