[MSVC][x86] Failed to build with error C2488 'naked' can only be applied to non-member function definitions

[NEIL-smtg]

Description:

Note:
To reproduce this, you'll need wait for VS 2022 17.12 Preview or later version to ship which will contain this change.

Recently, we have been building this project using the latest build of MSVC, and we have encountered the following error:

Serious-Engine\Sources\Engine\Base\CTString.cpp(511,35):
error C2488: 'CTString::ScanF': 'naked' can only be applied to non-member function definitions

Reproduction Step

1. git clone https://github.com/Croteam-official/Serious-Engine.git
2. cd /d C:\gitP\Croteam-official\Serious-Engine\Sources
3. msbuild /p:Platform=Win32 /p:Configuration=Release /p:PlatformToolset=v143 All.sln /t:Rebuild /m /p:BuildInParallel=true 2>&1

Expected Behavior

It compiles.

Actual result

Serious-Engine\Sources\Engine\Base\CTString.cpp(511,35): 
error C2488: 'CTString::ScanF': 'naked' can only be applied to non-member function definitions

Complete build log:
Build.log

Other information

This is the narrowed down repro, test.cpp:

struct Foo {
    __declspec(naked) void func1() {} // gets C2488
    void func2();
    __declspec(naked) static void func3() {} // gets C2488
};

__declspec(naked) void Foo::func2() {} // should also get C2488

repro command:

cl /c test.cpp

For current version, you will only ger error C2488 on line 2 and 4. For the upcoming version of VS, the last line will be also getting the error C2488.
