The following patch fixes the problem for me:

+++ standard.c 2015-09-30 13:29:00.826968000 +0300

FreeBSD manual page for getaddrinfo() is uncertain how to treat AI_PASSIVE when
hostname parameter is non-NULL (and this parameter is always non-NULL in
standard.c:str2ip()).
https://www.freebsd.org/cgi/man.cgi?query=getaddrinfo&sektion=3
On Linux manual page explicitly states that "If node is not NULL, then the
AI_PASSIVE flag is ignored."
So this change should be harmless for Linux.
What do you think?
