Description Don 2011-11-07 01:24:26 UTC 
Applies to both D1 and D2, at least as far back as 2.040. It's a forward reference error, triggered in this case by CTFE.

------------
class Base6900
{
    void foo() {}
}

class Derived6900: Base6900
{
    override void foo() { }
}

int test6900()
{
    Derived6900 d = new Derived6900;  // for github HEAD
    // Derived6900 d = null;   // for older versions
    d.foo();
    return 1;
}

static assert(test6900());
------------
test.d(8): Error: variable test.Derived6900.foo.this override cannot be applied
to variable
test.d(15):        called from here: d.foo()
test.d(19):        called from here: test6900()
test.d(19): Error: static assert  (test6900()) is not evaluatable at compile tim
