Created attachment 79057
  --> http://bugs.winehq.org/attachment.cgi?id=79057
test application source

Created very simple test application for EndUpdateResourceW.
Most likely it will not cover all possible invalid handle possibilities.

Compiled application with following parameters:
x86_64-w64-mingw32-gcc -Wall -g3 endupdate.c -static -lkernel32 -o
endupdate_64.exe

Wine was patched with patches on bug-46255.

Result on Windows 11:
C:\temp>ver

Microsoft Windows [Version 10.0.26100.4652]

C:\temp>endupdate_64.exe
Ret val:0 LastError:87
Ret val:1 LastError:0

C:\temp>

Result on Wine:
> WINEPREFIX=~/wine64 WINEARCH=win64 ~/wine64/wine --version
> wine-10.12-91-ge44737278a4
> WINEPREFIX=~/wine64 WINEARCH=win64 ~/wine64/wine cmd.exe
> Microsoft Windows 10.0.19045

C:\temp>endupdate_64.exe
Ret val:0 LastError:6
Ret val:0 LastError:6

C:\temp>


Test application source attached.
