           Summary: extern(C++) can not handle structs as return types
           Product: D
           Version: 2.014
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Keywords: wrong-code
          Severity: normal
          Priority: P2

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();
}
