  2. open a clean VS2019 x86 prompt and browse to D:\Chakra\src
  3. set CL=/std:c++latest
  4. msbuild /m /p:Platform=x86 /p:Configuration=Test /p:WindowsTargetPlatformVersion=10.0.18362.0 Build\Chakra.Core.sln /t:Rebuild

研究方向
Investigate the warning C4499 reported on lines 1558483-1558487 of JsrtContextCore.i. The fix likely involves adding a pragma to disable the warning around those lines. Check for similar patterns in the codebase. Consider using #pragma warning(push) and #pragma warning(disable: 4499) to suppress the warning for those template specializations. Verify that the fix compiles without errors on Windows with /std:c++latest.
