IntelliSense not handling constexpr float types properly (starting from extension 1.17.2)

rsarrazin2 commented 1 year ago

Environment

OS and Version: Ubuntu 20.04 @ WSL2
VS Code Version: 1.81.1
C/C++ Extension Version: >= 1.17.2
If using SSH remote, specify OS of remote machine: WSL2 @ Windows 11

Bug Summary and Steps to Reproduce

Bug Summary: IntelliSense reports errors (at least on constexpr literals) that the compiler doesn't.

Steps to reproduce:

Clone the minimum viable example.
Build it using the CMake extension (works probably as well when manually running CMake).
Open example.cpp.
If not happened automatically, run the "C/C++: Run Code Analysis on Active File" command.
You'll see the 4 IntelliSense errors that aren't reported by the compiler:

Expected behavior:

No Intellisense errors shall be displayed.

Notes:

Interestingly the errors affect both float and double literals, and the 0 literal doesn't show the error.
Reverting to any version < 1.17.2 (e.g. 1.16.3) solves the problem.
Issue opened upon suggestion by @Colengms in #11351, in this comment.

Note that v1.18.5 still presents the issue.

This issue is about to celebrate its first birthday but is unfortunately still present in v1.21.6. Kindly requesting to reconsider for prioritization.
