<pre>
    This simple code does not trigger a -Wshadow warning in clang++ 17.0.2, however g++ 8.5 emits a warning:
```c++
void f()
{
    int* ptr=nullptr;
    const auto& lambda=[&]()
    {
        int* ptr=nullptr;
    };
}
```
When explicitly capturing "&ptr", a warning is emitted by clang.

If using -Wshadow-all, clang emits a -Wshadow-uncaptured-local warning, although ptr is clearly captured.

```console
lambda_capture.cpp:6:14: warning: declaration shadows a local variable [-Wshadow-uncaptured-local]
        int* ptr=nullptr;
             ^
lambda_capture.cpp:3:10: note: previous declaration is here
    int* ptr=nullptr;
         ^
1 warning generated.
```
