mdspan

Environment

• OS and Version: Windows 11
• VS Code Version: 1.82.0-insider
• C/C++ Extension Version: 1.16.3

Bug Summary and Steps to Reproduce

Bug Summary: I am trying to use the mdspan in VSCode. I am using the parameters in Godbolt example and made a test. The code compiles without warnings or errors, however, VSCode intellisense shows an error. I have matched the compile flags with VScode c_cpp_properties.json, however, the error still persists.

Steps to reproduce:

1. Go to 'https://github.com/danchitnis/mdspan-test'
2. Close and open with VSCode
3. modify the c_cpp_properties.json, to point to your g++ compiler
4. See the highlighted errors in VSCode

Expected behavior: No highlighted errors

@danchitnis Thank you for submitting this issue. I was able to reproduce it with the sample project.

We'll further investigate to see if we can simplify the repro for our IntelliSense engine team to look at.

Any progress on this? Getting this error from Intellisense even though my code compiles using MSVC
