Intellisense doesn't recognise inline variables from headers files

[TerensTare]

Type: LanguageService

Describe the bug

• OS and Version: Windows 10
• VS Code Version: 1.52.1 (user setup)
• C/C++ Extension Version: 1.2.0-insiders2
• Other extensions you installed (and if the issue persists after disabling them):
  • twxs.cmake
  • ms-vsocde.cmake-tools
  • jeff-hykin.better-cpp-syntax
  • coenraads.bracket-pair-colorizer-2
  • usernamehw.errorlens The issue persists even after disabling these extensions
• Does this issue involve using SSH remote to run the extension on a remote machine?: No
• A clear and concise description of what the bug is, including information about the workspace (i.e. is the workspace a single project or multiple projects, size of the project, etc). The *.workspace file is on the ./vscode folder and is single-directory only. There is a header file that declares some inline variables inside a namespace. When trying to use these variables on a .cpp file, Intellisense doesn't show these variables as a suggestion, and gives an error when I just try to rewrite myself.

Steps to reproduce

1. Create a header file on the main directory with the following content.

```cpp // my_header.hpp #ifndef MY_HEADER #define MY_HEADER namespace my { inline struct tag_type {} tag; } #endif ```

2. Create a source file on the same dir with the following content.

```cpp // main.cpp #include "my_header.hpp" using my::tag; // error int main() { auto a = my::tag; // error } ```

Expected behavior I expected the Intellisense to suggest me my::tag when typing my::. Also I expected to see no error (I get: namespace "my" has no member "tag") as the variable exists. The example compiles fine with MSVC 14.28.29333,

Hi @TerensTare . I pasted the code you provided into a header and cpp source file, and am not able to repro the issue.

Is it possible there is some other issue here, such as another header that has already defined MY_HEADER?

Can you provide a simple repro in the form of a GitHub repo we can clone?

[TerensTare]

Hi @Colengms . Thanks for the response. I checked the include guards and there is no #define collision. I was getting the error on this repo, specifically on main.cpp

[TerensTare]

I think I owe a deep apology to everybody included in this. The problem came from a template-d struct from the project. I recently deleted a member variable from that struct, and deleted the closing brace of the struct. This apparently lead to the series of errors, as they disappeared soon as I added the missing }. Thank you Colenmgs (again).
