Description

Environment

cpptools — References on the destructor mv::Vec2::~Vec2() collapse to the whole type

Field Value
Symbol (spec id) dtor-Vec2
Declaration ~Vec2(); (destructor)
Query position 1 src/mathvec.h:15:6 (cursor on Vec2, immediately after the ~)
Query position 2 src/mathvec.h:15:5 (cursor on the ~, immediately before Vec2)
Affected LSP request textDocument/references
Repro archive P1-dtor-Vec2.zip (this folder)

Summary

For query position 1

Find All References on the destructor of mv::Vec2 returns every mention of the Vec2 type instead of the two destructor sites — even though the cursor is on the destructor name after the tilde. Observed in VS Code with the C/C++ extension (cpptools).

For query position 2

Find All References on the destructor of mv::Vec2 returns no results. Observed in VS Code with the C/C++ extension (cpptools).

Environment

  • Editor: Visual Studio Code 1.33.5
  • Extension: C/C++ (ms-vscode.cpptools), default IntelliSense engine
  • Language standard: C++20 (freestanding fixture; no STL/toolchain required)

Steps to reproduce

  1. Extract P1-dtor-Vec2.zip and open the cpp-project folder in VS Code (C/C++ extension enabled).
  2. Optionally configure with CMake Tools (preset cdb); the fixture also parses under default C++20 IntelliSense.
  3. Open src/mathvec.h and place the cursor either immediately after the ~ in ~Vec2();, on Vec2 (line 15, col 6); or immediately before the ~, on the tilde itself (line 15, col 5).
  4. Invoke Find All References (Shift+Alt+F12).

Expected vs actual

Source Result count
Expected (both positions) 2
cpptools — query position 1 39
cpptools — query position 2 0

Expected (2): the declaration (mathvec.h:15) and the out-of-line definition (mathvec.cpp:11, Vec2::~Vec2()).

Actual — query position 1 (39): every occurrence of the Vec2 type (the same 39-item set as the constructor queries). Placing the cursor after the ~ does not restrict the query to the destructor — it collapses to "all mentions of the type."

Actual — query position 2 (0): no results at all.

Why it matters

Destructor references are used to reason about lifetime and teardown. Returning the whole type population makes that impossible and is especially surprising given the cursor is unambiguously on the destructor.

Research direction

Start with the extracted P1-dtor-Vec2.zip fixture, especially src/mathvec.h:15 and the destructor definition at src/mathvec.cpp:11. Run Find All References at both cursor positions and trace the textDocument/references handling; done means both positions return exactly the declaration and out-of-line definition, rather than 39 type references or no results.
