Syntax highlight issue with comments

[dxdxdt]

Issue Type: Bug

Comments in /usr/include/linux/if_ether.h are highlighted wrong. Obviously, the code compiles just fine, but Code thinks that they're malformatted.

VS Code version: Code 1.50.1 (d2e414d, 2020-10-13T14:44:48.716Z)
OS version: Linux x64 5.8.16-200.fc32.x86_64

A real bug in VS Code.

Confirmed issues with C and C++ files.

This issue happens with only the #define preprocessor

Does this happen when all the extensions are disabled: YES

I wonder if this is related to the behavior I see in groovy files. It seems similar in that it goes red related to / characters.

In my case it doesn't happen in c, cpp, or cs files.

Does this happen when all the extensions are disabled: YES

Also note that the incorrect line will highlight correctly if the comment is removed from the end of it. There appears to be an interaction between the / in code and the // after the closing brace.

@stevenhiner a different grammar is used for groovy, so I wouldn't expect the issue to be related.

Thanks for the small repro @thunder-coding! Looks like this is an issue in the grammar we use for C++. I created an issue in the upstream repository: jeff-hykin/better-cpp-syntax#527
