Description
I switched to 1.13.1. I can confirm that the reported issue is fix.
Now I'm experiencing two more issues with the same "test".
- Performance when CTRL+Click on std::view is very poor on my machine. It takes very long to load the IntelliSense data, and then the line that should appears under std::range::view feels to no appear: appears disappears. This feature behaves erratically. This sluggish behavior is present in the Clang configuration. In the GCC configuration the performance is much smoother. IMO
- In the GCC configuration now I am seeing this (I haven't noticed this error before):

Research direction
Start by reproducing the CTRL+Click behavior on std::view in the Clang configuration and the reported error in the GCC configuration, using the test described in the issue. Compare IntelliSense loading and underlining in both configurations; done means the Clang interaction is responsive and stable and the GCC error is resolved.
