[Bug 20368] New: sockaddr_in6 wrong size; causes chromium's net_unittests HostResolverImplTest.NumericIPv6Address test case to fail

http://bugs.winehq.org/show_bug.cgi?id=20368

Summary: sockaddr_in6 wrong size; causes chromium's
                    net_unittests HostResolverImplTest.NumericIPv6Address
                    test case to fail
           Product: Wine
           Version: 1.1.31
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Keywords: download, source, testcase
          Severity: normal
          Priority: P2
         Component: winsock
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Running chromium's base_unittests.exe fails all over the place
unless it can find the source tree, but even if you put the
source tree where it wants it, it fails various tests.  The
first one in the list is 
HostResolverImplTest.NumericIPv6Address 
which fails with
[11:71:1014/112257:84976129:FATAL:address_list.cc(76)] Check failed:
sizeof(sockaddr_in6) == info->ai_addrlen (28 vs. 24)

Here's the failing bit of the testcase, extracted into a nearly plain C
program:

#undef NDEBUG
#include <ws2tcpip.h>
#include <stdio.h>
#include <assert.h>
#pragma comment(lib, "ws2_32.lib")
int main(int argc, char **argv)
{
    WSADATA wsaData;
    int err;
    struct addrinfo *ai = NULL;
    struct addrinfo hints;
    err = WSAStartup(MAKEWORD(2, 2), &wsaData);
    assert(err == 0);
    ZeroMemory( &hints, sizeof(hints) );
    hints.ai_family = AF_UNSPEC;
    hints.ai_socktype = SOCK_STREAM;
    hints.ai_protocol = IPPROTO_TCP;
    err = getaddrinfo("2001:db8::1", "10000", &hints, &ai);
    assert(err == 0);
    assert(ai->ai_addrlen == sizeof(struct sockaddr_in6));
    freeaddrinfo(ai);
    WSACleanup();
    return 0;
}
Compiled on Windows, this succeeds on Windows but fails on Wine.
