Descrizione

Environment
  • OS and Version: Windows 11, 24H2
  • VS Code Version: 1.97.2 (e54c774e0add60467559eb0d1e229c6452cf8447)
  • C/C++ Extension Version: 1.23.6
Bug Summary and Steps to Reproduce

Bug Summary: Intellisense gives an error on structured binding declaration on legal code, specifically the error is std::tuple_size<"const Typename">::value is not a valid integral constant-expression, there is an existing issue already #2597 for this same error and it is reported as completed, however this still persists, with a slight difference. The original bug report's code works fine, however including any header will cause the error to reapper.

Steps to reproduce:

  1. Create a new CMake project
cmake_minimum_required(VERSION 3.30)
project(Test)

add_executable(Test)
target_sources(Test PRIVATE main.cpp)

set_target_properties(Test PROPERTIES
  CXX_STANDARD 23
  CXX_STANDARD_REQUIRED ON
)
  1. Write the following C++ code
#include <iostream>

struct Point {
  int x;
  int y;
};

const auto [x, y] = Point(1, 2);
  1. Error will appear near the structured binding declaration as std::tuple_size<"const Point">::value is not a valid integral constant-expression

Expected behavior:
No error should appear, code is perfectly legal as per the C++17 and newer standards

Direzione di ricerca

Riproduci la diagnostica in main.cpp usando il progetto CMake mostrato, le impostazioni C++23, la configurazione clang-cl e un header iostream incluso. Inizia esaminando come IntelliSense gestisce la dichiarazione di structured binding e la relativa diagnostica tuple_size. Il lavoro è completato quando la dichiarazione valida non produce un errore erroneo con la configurazione indicata.

Scritto dal modello di indicizzazione a partire dal testo della issue.
