squid 3.3.0.2 abort in Ip::Address::GetAddrInfo

I've encountered something strange when running squid 3.3.0.2 built using these options:

  $ ./configure --with-default-user=squid --bindir=/usr/local/sbin --sbindir=/usr/local/sbin --datadir=/usr/local/etc/squid --libexecdir=/usr/local/libexec/squid --localstatedir=/var/squid --sysconfdir=/usr/local/etc/squid --with-logdir=/var/log/squid --with-pidfile=/var/run/squid/squid.pid --enable-auth --enable-build-info --enable-loadable-modules --enable-removal-policies=lru heap --disable-epoll --disable-linux-netfilter --disable-linux-tproxy --disable-translation --enable-auth-basic=DB MSNT MSNT-multi-domain NCSA PAM POP3 RADIUS fake getpwnam NIS --enable-auth-digest=file --enable-external-acl-helpers=file_userip unix_group --enable-auth-negotiate=kerberos wrapper --enable-auth-ntlm=fake smb_lm --enable-storeio=diskd rock ufs aufs --enable-disk-io=AIO Blocking DiskDaemon IpcIo Mmapped DiskThreads --enable-log-daemon-helpers=file --enable-url-rewrite-helpers=fake --disable-snmp --enable-ssl --with-openssl=/usr --enable-ssl-crtd --enable-htcp --disable-forw-via-db --disable-cache-digests --enable-wccp --enable-wccpv2 --disable-eui --enable-ipfw-transparent --disable-pf-transparent --disable-ipf-transparent --disable-follow-x-forwarded-for --disable-ecap --enable-icap-client --disable-esi --disable-kqueue --enable-stacktraces --prefix=/usr/local --mandir=/usr/local/man --infodir=/usr/local/info/ --build=i386-portbld-freebsd8.3

It's aborting in Ip::Address::GetAddrInfo() with a strange value for the force parameter:

$2 = 6

It has me puzzled, since the force parameter should default to 0, shouldn't it?
