References and Call Hierarchy are wrong for constructors

Extrae P1-ctor-Widget-int.zip y reproduce las consultas de src/widget.h contra los sitios de construcción de main.cpp y la definición en widget.cpp. Compara textDocument/references y callHierarchy/incomingCalls con los recuentos esperados documentados. Se considera terminado cuando el constructor devuelve únicamente su declaración, definición y dos sitios de construcción, y aparecen ambos llamadores entrantes.

Environment

cpptools — References and Call Hierarchy are wrong for the constructor ui::Widget::Widget(int)

Summary

Two independent defects hit the same constructor when it is queried in VS Code with the C/C++ extension (cpptools):

1. Find All References returns every mention of the Widget type instead of the actual construction sites (over-count).
2. Show Call Hierarchy → Show Incoming Calls returns nothing, so the constructor looks like it is never called (false "no callers").

The correct (expected) results are shown below.

Environment

• Editor: Visual Studio Code 1.33.5
• Extension: C/C++ (ms-vscode.cpptools), default IntelliSense engine
• Language standard: C++20 — the fixture is freestanding (no STL/toolchain needed to parse)

Steps to reproduce

1. Extract P1-P1-ctor-Widget-int.zip and open the cpp-project folder in VS Code with the C/C++ extension enabled.
2. Optionally configure with CMake Tools (preset cdb) so cpptools picks up compile_commands.json; the freestanding fixture also parses under default C++20 IntelliSense.
3. Open src/widget.h, place the cursor on Widget in explicit Widget(int id); (line 13, col 14).

Defect 1 — textDocument/references

4. Invoke Find All References (Shift+Alt+F12).

Expected (4): the declaration (widget.h:13), the out-of-line definition (widget.cpp:9, Widget::Widget(int id)), and the two Widget(int) construction sites in main.cpp — the static ui::Widget storage(42); initializer in allocWidget() and ui::Widget b(7); in main().

Actual (28): every occurrence of the ui::Widget type — the typedef, the g_current pointer, the takeWidget/makeDefault/allocWidget/asConst parameter and return types, the Serializer<ui::Widget> specialization, and the type-mention lines in widget.cpp — none of which construct an object. A references query on the constructor collapses to "every mention of the enclosing type."

Defect 2 — callHierarchy/incomingCalls

5. With the cursor at the same position, invoke Show Call Hierarchy and expand Incoming Calls.

Expected (2): incoming calls from allocWidget() (the storage(42) construction at main.cpp:29) and from main() (the b(7) construction at main.cpp:55).

Actual (0): the Call Hierarchy view shows no callers, i.e. the constructor appears to be dead.

Why it matters

• The empty incoming-calls result is a false "no callers" on live code: an automated agent (or a developer) can conclude Widget(int) is never used and delete/prune construction paths that are actually exercised.
• The reference over-count means "where is this object constructed?" cannot be answered, the list is dominated by unrelated type mentions.
