 # Printing a pointer into a virtual base of a larger object used to do
 # pointer adjusment directly into the value being printed, in-place
 # (and did it wrong, too).  Print the pointer, and then access the
 # value history to check the pointer value is not changed.  If it had
 # been changed, then we'd not be able to find the real type anymore.
