I just found out that wine has a test for it, but it has been commented out:


     if (0)
     {
     /* this test crashes on WinNT4
      */
     boolret = VerQueryValueA( pVersionInfo, backslash, (LPVOID 
*)&pFixedVersionInfo, 0);
     ok (boolret, "VerQueryValue failed: GetLastError = %u\n", 
GetLastError());
     }

Cheers,
Rafael
