Errors if I use char[] string inisialisation using std::filesystem::path
Environment
- OS and Version: Windows 11 22H2
- VS Code Version: 1.81.1
- C/C++ Extension Version: 1.17.5
I use Clang 16.0.5 under MSYS2 enviroment (Clang profile (UCRT runtime))
Bug Summary and Steps to Reproduce
Using anonymous std::string initialization using std::filesystem::path, VS Code shows an error; however, I can successfully compile my project without any warnings or errors.
Example:
std::filesystem::path path1{"mypath.ext"};
std::filesystem::path path2(std::string("mypath.ext"));
std::filesystem::path path3 = path2 / "some";
std::filesystem::path path4 = path2;
path4.replace_extension(".ext");
path1:

path2 works; path3:

In all cases, if I replace "mystring" with std::string(mystring) it errors will disappear.

Hi @wusikijeronii . Thanks for reporting this. It appears to be related to a bug in our IntelliSense engine, which is shared with Visual Studio. I've opened an internal bug against VS for this (1879043).
I can confirm this error also occurs on Visual Studio Code for macOS.
The code below compiles without issue, but Intellisense reports an error.
