<pre>
    LLDB is crashing when im trying to execute `frame variable` command and there is instance of a class that contains shared_ptr inside of it

Platform: Windows 11 23H2 
Compiler that used to build executable: MSVC v19.41

What version of lldb were tested: 
lldb v19.0 (installed from visual studio installer)
lldb v20.0 (builded from sources on 17 of december 2024)

Minimal code to reproduce bug
```cpp
#include <iostream>

class Test
{
public:
 Test(std::shared_ptr<int> v)
      : value(v)
  {}

 std::shared_ptr<int> GetValue() { return value; }

private:
 std::shared_ptr<int> value;
};

int main()
{

  std::unique_ptr<int> test = std::make_unique<int>(25);

  std::cout << "Test " << *test << std::endl;

  Test t(std::make_shared<int>(42));

  std::cout << "Test2 " << *t.GetValue() << std::endl;
}
```

Actions to reproduce this bug
1) Build executable
2) Attach lldb to it with `lldb app.exe`
3) Set breakpoint on main
4) run program to hit the breakpoint
5) execute command `frame variable`
6) expect crash
