Running an app on a wifi-only iPad with iOS 11.3 (15E216) connected to an IPv4-only network. Application configured with AddressSanitizer fails on calls to extractAddress_ipv6(). This call should never happen as the device does not have an IPv6 address.

I've seen something similar on another iPad with an IPv6 address bound to the LTE radio, but this is a first on a Wifi only device. See this: https://forums.developer.apple.com/thread/111661 for background.

Here's the backtrace:
