C++ code:
```C++
#include <iostream>
class A {
public:
void foo() { std::cout << "foo" << std::endl; }
};
int main() {
auto a1 = new A;
a1->foo(); // prints "foo"
A a2;
a2.foo(); // prints "foo"
delete a1;
}
```
D code:
```D
@safe:
import std.stdio;
class A {
void foo() { writeln("foo"); }
}
void main() {
auto a1 = new A;
a1.foo(); // prints "foo"
A a2;
a2.foo(); // Segmentation fault
}
```
I didn't expect to see a segmentation fault in the code, which is
a straightforward conversion from C++. And especially not with
the use of the `@safe` attribute. What's going on here?
