I did run wine like:

WINEDEBUG=+relay wine /path/to/nslookup.exe 2>&1 | less

and looked in the output what it was doing. It is doing more, especially
if the value is not found. Some of that looks like security/permission
checks, it may not be that easy to decipher those. That is why the older
version of nslookup works easier, I think.

Because of the what nslookup works it is to be expected to do the low
level DNS queries itself. I am not convinced that an ordinary
application would go into this kind of trouble, they usually use some
high level api like winsock. But then, I do not know your app.

Your winedbg registry set-up is out of date. It needs to be something
like ( ~/.wine/system.reg):

| [Software\\Microsoft\\Windows NT\\CurrentVersion\\AeDebug] 1102496326
| "Auto"="1"
| "Debugger"="winedbg %ld %ld"

Because wine is using the built-in dll. No need to try native, the
winsock dll's cannot be used that way.  A patch to implement getaddrinfo
was sent yesterday is but is not committed yet.
