Compile the program below with dmd -debug -g, and step inside Bobo::coco and Foo::coco respectively, using either GDB or ZeroBUGS.

The struct / classes are shown as opaque (GDC generates the correct information).

import std.stdio;

struct Bobo
{
    int a;

    void coco()
    {
        writefln("Bobo::coco");
        a += 1;
    }
};


class Foo
{
    int a;

    void coco()
    {
        writefln("Foo::coco");
        a += 1;
    }
};

void main()
{
    Bobo b;
    b.coco();

    Foo i = new Foo;
    i.coco();
}
