https://bugzilla.redhat.com/show_bug.cgi?id=1124368
Bug ID: 1124368
Summary: mingw32-crt has wrong value for in6addr_loopback
Product: Fedora EPEL
Version: epel7
Component: mingw32-w32api
Assignee: rjones(a)redhat.com
Reporter: chris(a)edesix.com
QA Contact: extras-qa(a)fedoraproject.org

The value of _in6addr_loopback is wrong. It should be ::1, but is :: (all
zeros). See the "Contents of section .rdata" in the objdump snippet below...

I've logged this issue under mimgw32-w32api because there is no mingw32-crt
component.

Chris.
