There is an exception in the standard (page 177, lines 17-21):
> If a corresponding list item of the original list item is in the enclosing device data
> environment, the new device data environment uses the corresponding list item from the

So, the pointer 'a' should inherit map-type ALLOC from the enclosing
device data environment.
