LunaDll
Tested on Wine 7.15 and 7.17. I've managed to get the same crash for multiple
executables.
Reproduction steps for SMBXLauncher.exe:
1. Download SMBX2 from:
https://wohlsoft.ru/docs/SMBX2/SMBX2b4.4.1%20Installer.exe (SHA-256:
4cd2047e01df7e9a4155e7ebed890f29a38b424ef12ebcc77030bfacbaf9399c) and install
it in any Wine prefix
2. Create a new 64 bit Wine prefix
3. If Wine >= 7.16, install Visual C++ 2013 Redistributable (winetricks
vcrun2013) (workaround for https://bugs.winehq.org/show_bug.cgi?id=53672)
4. Download x64dbg from
https://github.com/x64dbg/x64dbg/releases/download/snapshot/snapshot_2022-09...
(SHA-256: dcd3b74faa6e845a533756f778a2c7eb020f130239bf3e7cbb881acd91d3e76b) and
extract the release folder
5. Run x32/x32dbg.exe
6. File>Open then choose SMBX2/data/SMBXLauncher.exe
7. Click on Run (Right arrow button next to the pause button) multiple times
8. x32dbg should crash
Reproduction steps for LunaLoader.exe:
1. Download SMBX2 from:
https://wohlsoft.ru/docs/SMBX2/SMBX2b4.4.1%20Installer.exe (SHA-256:
4cd2047e01df7e9a4155e7ebed890f29a38b424ef12ebcc77030bfacbaf9399c) and install
it in any Wine prefix
2. (Facultative) Replace SMBX2/data/LunaDll.dll by the one attached to this bug
report. Both versions of LunaDll produce the same crash but at different times.
3. Create a new 64 bit Wine prefix
4. If Wine >= 7.16, install Visual C++ 2013 Redistributable (winetricks
vcrun2013) (workaround for https://bugs.winehq.org/show_bug.cgi?id=53672)
5. Install Direct3D 10.1 Extensions (winetricks d3dx10_43), DirectSound
(winetricks dsound) and the Visual Basic 6 runtime (winetricks vb6run). These
are required by SMBX2.
6. Download x64dbg from
https://github.com/x64dbg/x64dbg/releases/download/snapshot/snapshot_2022-09...
(SHA-256: dcd3b74faa6e845a533756f778a2c7eb020f130239bf3e7cbb881acd91d3e76b) and
extract the release folder
7. Download DbgChild from
https://github.com/therealdreg/DbgChild/releases/download/beta10/DbgChild.Be...
(SHA-256: f17f588795d8f5f94d71335a8acfa58946bb03a94a5637be7f3e804c652ea2b4) and
extract the contents of the release folder in the release folder of x64dbg
8. Download DbgChild patched executables from
https://bugs.winehq.org/attachment.cgi?id=73108 (SHA-256:
69e34736c0ab844b675cfac7bd3cf547204cdfb43799e312e4bb14c96c9a9c5c) and extract
the contents of the release folder in the release folder of x64dbg (workaround
for https://bugs.winehq.org/show_bug.cgi?id=53700)
9. Run x32/x32dbg.exe
10. Plugins>dbgchild then check Auto from x32dbg/x64dbg Hook process creation,
Auto from x32dbg/x64dbg Unpatch NTDLL entry and Launch from x32dbg/x64dbg
NewProcessWatcher without ask
11. File>Open then choose SMBX2/data/LunaLoader.exe
12. Click on Run (Right arrow button next to the pause button) multiple times,
