Following code throws an error by the native C compiler:

[SimpleType]
struct Foo {
	float bar;	
	public Foo (float bar) {
		this.bar = bar * 2;
	}	
	public void add (float a) {
		this.bar += a;
	}	
	public float get_bar () {
		return this.bar;
	}
}
void main () {
	Foo foo = Foo (2.5f);
	foo.add (3.5f);
	stdout.printf ("%f\n", foo.get_bar ());
}

The error occurs in the foo_init function, when the self parameter is passed to memset. The self parameter should cast to a void* pointer;
