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

```
There should be diagnostics logs in my Temp folder according to this message
```
LLDB diagnostics will be written to C:\Users\{USER}\AppData\Local\Temp\diagnostics-897c9d
```
But `diagnostics.log` file is competly empty.
