2490 – extern(C++) can not handle structs as return types

The code below shows that the this pointer gets corrupted when this code compiles and runs. Sample output:
Bar = 0x81c33a8
This = 0xbf8dce20
cpp file:
#include <iostream>
struct foo{
 int i;
 int j;
};
class bar{
public:
 virtual foo getFoo(){
 std::cout << "This = " << this << std::endl;
 foo f;
 return f;
 }
};
bar* newBar(){
 bar* b = new bar();
 std::cout << "Bar = " << b << std::endl;
 return b;
}
d file:
extern(C++){
 struct foo{
 int i;
 int j;
 }
 interface bar{
 foo getFoo();
 }
 bar newBar();
}
void main(){
 bar b = newBar();
 foo f = b.getFoo();
}
