Error parsing intrin.h, included by other standard headers

I've recently started getting this issue on any data structure that I try seeing the layout of:

It seems that pretty much any standard header eventually includes intrin.h, which causes that issue.

The extension used to work fine on this project, so it was either a recent update or updating Visual Studio to 16.8.2 (sorry, those two things happened at the same time, not sure who's at fault).

Sadly, this is a regression with Visual Studio. There isn't much I can do on my end a part from waiting and hoping the submitted fix for 16.9 works.

Thanks for letting me know! The diff provided on that thread serves as a workaround for me.

New VS was released this week.

New VS was released this week.

New VS version fixed this bug for me, I can use it normally now.

Thanks @Zingam and @DJLink for validating with the latest VS release!
