Environment
- OS and Version: Fedora Linux 44
- VS Code Version: 1.123.0
- C/C++ Extension Version: 1.32.2
Bug Summary and Steps to Reproduce
Bug Summary: IntelliSense falsely reports an error when attempting to create an std::span<const T> from std::vector<T>. Code compiles without issue by GCC and Clang.
Steps to reproduce:
- Create a file with the following sample code:
#include <print>
#include <span>
#include <vector>
int main()
{
std::vector<int> v = { 1, 2, 3 };
std::span<const int> s(v);
std::println("{}", s);
}
- Set C++ properties accordingly (C++23 mode)
- The following error is reported:
no instance of constructor "std::span<_Type, _Extent>::span [with _Type=const int, _Extent=18446744073709551615UL]" matches the argument list
argument types are: (std::vector<int, std::allocator<int>>)
Expected behavior: No error should be reported.
Workaround: This error is not reported if intelliSenseMode is set to linux-clang-x64 with compilerArgs -stdlib=libc++. Perhaps linked to #14464? With the above sample, a different false error about std::println is reported, but that is probably a separate issue.
