segfault while proxying ssh on OpenBSD-current [OpenSSH_7.1 LibreSSL 2.3.2]

Hi,
I don't know if it is an OpenBSD specific issue. I got a segfault in proxychains-ng when using a socks5 proxy to tunnel a ssh connection. SSH print "get_hostfile_hostname_ipaddr: getnameinfo failed" which causes the segfault.

tail -n 1 /tmp/px.conf

socks5 127.0.0.1 8888

./proxychains4 -f /tmp/px.conf ssh -vvvvvv root@192.168.130.5

Below is the gdb output with DEBUG activated. A more verbose output with SSH debug activated on http://pastebin.com/ZEwxmfYm

Start by reproducing the reported command with proxychains4, /tmp/px.conf, and an SSH connection through the SOCKS5 proxy on OpenBSD-current. Trace the logged proxy_getaddrinfo, pc_getnameinfo, and proxy_freeaddrinfo paths around the getnameinfo failure; done means the connection no longer segfaults and SSH can proxy successfully.
