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);
    }
