    The following example:

```cpp
class ExplicitThis {
  int f = 0;
public:
  ExplicitThis();
  ExplicitThis(ExplicitThis& other);

  ExplicitThis& operator=(this ExplicitThis& self, ExplicitThis const& other) {
    self.f = other.f;
    return self;
 }

  ~ExplicitThis();
};

void func(ExplicitThis& obj1) {
 obj1 = obj1;
}
```

crashes the analyzer (with assertions enabled and disabled) using the following command:

```
clang-19 -std=c++23 --analyze -Xclang -analyzer-config -Xclang aggressive-binary-operation-simplification=true -Xclang -analyzer-checker=alpha.cplusplus.InvalidatedIterator -Xclang -analyzer-output=text file.cpp
```

Stack trace:
