An ancient bug: same ICE on D1.020 as on D2.036
TEST CASE:

struct Ashes {
    int ashes = cast(int)0;
}
void funky (Ashes s = Ashes()) {}

void funk() {
   funky();
}


PATCH: This patch also fixes the closely related bug 3422.
 (The semantic is for this bug. The implicit cast is for bug 3422.
The assert is just a precaution).
expression.c line 3271.

        {    e = v->type->defaultInit();
        e->loc = loc;
        }
        offset = v->offset + v->type->size();
    }
+   assert(v->type);
+    e= e->semantic(sc);
+    if (e->type !=v->type) e = e->implicitCastTo(sc, v->type);
    elements->push(e);
    }

The fix for this is somewhat more complicated than the patch. The problem is the scope of the field initializer is the scope of where the field appears, not where the field is used. I'll see if I can fix it.
