Stack trace produced before segfault
```c++ (-std=c++17)
#include <string>
#include <optional>
using namespace std;
class A {
public:
optional<string> Label;
A() {}
};
class B : public A {
public:
B() {}
void foo();
};
void B::foo() {
return;
}
int main() {
B *Obj = new B();
Obj->foo();
return 0;
}
```
The above code when compiled with
g++ (GCC) 11.1.0
and tried to debug via
1. lldb version 12.0.1, and also with
2. lldb version 14.0.0 (https://github.com/llvm/llvm-project.git revision
3be3c944a5bacfd208b56853941b0fa4dec3ddcc)
clang revision 3be3c944a5bacfd208b56853941b0fa4dec3ddcc
llvm revision 3be3c944a5bacfd208b56853941b0fa4dec3ddcc
produces the following trace and crashes with segfault.
