Hi,
Does anyone see this as well? I've just upgraded to:
OpenBSD 5.8-current (GENERIC) #1164: Wed Sep 16 21:16:53 MDT 2015
dera...@i386.openbsd.org:/usr/src/sys/arch/i386/compile/GENERIC
and to openvpn-2.3.8 from packages but it segfaulted during connecting
by remote client. Then I've recompiled by hand with DEBUG='-g' from
ports and now running openvpn-2.3.8p1, but facing the same issue.
To be able to get core dump, needed to run openvpn as root, but the same
segfault happens when openvpn drops priviliges.
Before that I was running snapshot from Aug 13 with packages and I
didn't had that problem.
Let me know if you need any more info.
