[WS2_32_WINETEST] ws2_32:sock crashes on 2k3sp2 and WinXPSP3, if IPv6 is not present

Testing ws2_32_winetest.exe from 0.4.15-dev-7907-g95bf896 GCC8.4.0dbg x86

• Make sure that the IPv6 internet protocol is not installed (use just IPv4)
• Stop and disable the "IPv6 Helper service" via services.msc
• Stop and disable the "IPSec services" via services.msc
• then run

  ws2_32_winetest.exe sock

Expected result
The test is expected to run till the end, until it will write the line how many tests were run, how many failed, and how many were skipped.
You can get bonus-points (but is not required to resolve the ticket) if you manage to: all IPv6 related tests should ideally be skipped in such a config (and not fail)

Observed result
On WinXPSP3 the test will crash while executing the function verify_ipv6_addrinfo(), The last output looks like that

on 2k3sp2 the test will crash like that (differently): 2K3_SP2_crash.png

Sidenote
Those crashes do not happen on our WHS bot, I assume we do have the IPv6 configured to be enabled over there, and the mentioned services to be running.
