This code doesn't compile:

interface VisualElement {
   void draw();
}

interface Actor {
}

interface VisualActor : Actor, VisualElement {
}

class Sprite3 : Actor, VisualActor {
    override void draw() { }
}

The error message is:

Error: function test.Sprite3.draw does not override any function

If I comment out the implementation of draw I get:

Error: class test.Sprite3 interface function VisualElement.draw isn't implemented

Of course, both of these can't be true at the same time :o). The original program should compile and run properly.

Compiler bugs are not usually this silly. Applies to D1 as well. This also fixes bug 3023. I suspect it probably fixes some other bugs too -- I'm amazed multiple inheritance has worked at all. class.c, line 1198. // Skip if b has already appeared for (int k = 0; k < i; k++) { - if (b == interfaces[i]) + if (b == interfaces[k]) goto Lcontinue; } -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

I'll try to look harder.
