IPv6Address::to_string() return a local address

[LubinLew]

Function return a local address (buffer), Is this correct?

string IPv6Address::to_string() const {
    char buffer[INET6_ADDRSTRLEN];
    #ifdef _WIN32
        // mingw on linux somehow doesn't have InetNtop
        #ifdef _MSC_VER
            if (InetNtopA(AF_INET6, (PVOID)address_, buffer, sizeof(buffer)) == 0) {
                throw invalid_address();
            }
        #else
            ULONG sz = sizeof(buffer);
            if (RtlIpv6AddressToStringExA((const IN6_ADDR*)address_, 0, 0, buffer, &sz) != NO_ERROR) {
                throw invalid_address();
            }
        #endif
    #else
        if (inet_ntop(AF_INET6, address_, buffer, sizeof(buffer)) == 0) {
            throw invalid_address();
        }
    #endif
    return buffer;
}
