If you convert them to the common type before converting to void*, yes.
Otherwise it's the same situation as with parallel bases. I believe that
the intent of 5.10 was to talk about comparing using the same
pointer-to-class type, and that comparing via a pointer-to-void or some
other unrelated type should have different rules.

I suppose so. I've sent off a note.
