           Summary: "Script error: Handler not defined #FileIO" in "TKKG
                    1" (EN: Jennifer is Missing, DE: Katjas Geheimnis -
                    Tivoli)
           Product: Wine
           Version: 6.4
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ntdll
          Assignee: wine-bugs@winehq.org
          Reporter: bernhardu@mailbox.org
      Distribution: ---
Since wine-6.4 this application fails with this message:
    Script error: Handler not defined
    #FileIO
This is visible since this commit:
  commit af74bd31229e0f065448253b248ec0cb3b51af26

Unfortunately I am not able to revert this commit on current git.
I think this is the problematic area of the executable:
  004F12C9 push    offset aXobglu32Dll ; "xobglu32.dll"
  004F12CE call    ds:LoadLibraryA
  004F12D4 mov     ebp, eax
  004F12D6 test    ebp, ebp
  004F12D8 jz      short loc_4F1309
  004F12DA push    offset aMyloadlibrary3 ; "MyLoadLibrary32"
  004F12DF push    ebp             ; hModule
  004F12E0 call    ds:GetProcAddress
  004F12E6 mov     ecx, [esp+10h+arg_0]
  004F12EA push    ecx
  004F12EB call    eax
  004F12ED movzx   esi, ax
  004F12F0 test    esi, esi
  004F12F2 jnz     short loc_4F12FD
  004F12F4 push    ebp             ; hLibModule
  004F12F5 call    ds:FreeLibrary
  004F12FB jmp     short loc_4F1309
  004F12FD mov     [ebx], esi
Inside MyLoadLibrary32 it seems the application does a
16-bit KERNEL.95:LOADLIBRARY of fileio.dll,
which looks like it succeeds (retval=00000306).
Unfortunately for some reason the FreeLibrary is reached when it
was not before the above commit.
A +relay trace shows also a NtSetContextThread involved,
which got modified by above commit.
I tested with:
- https://archive.org/details/tkkg-1-jennifer-is-missing
- export WINEARCH=win32
- winecfg, set to Windows 95.
- Workaround for following error:
      "This program requires at least 3MB of free virtual memory to run"
  echo -e "MemTotal: 32768 kB\nMemFree: 32768 kB\nSwapTotal: 32768
kB\nSwapFree: 32768 kB\nBuffers: 0\nCached: 0" > my-meminfo.txt
  bwrap --dev-bind / / --dev-bind my-meminfo.txt /proc/meminfo wine
tkkg1_95.exe
