Elements on the operand stack are explicitly address-sized. From DWARF
1.11.1:
Each element of the stack is the size of an address on the target
machine.

That interpretation makes sense to me, but so does the one making it an
error. I suspect we will never run across code that exercises this. If
you want to change it, I have no objection.
