Actually, I take that back, sorry.  I forgot something:

I still think it'd be very good to have this covered
with a test.

I think it should be a matter of wrapping the printing
part of new tests (maybe only implref-struct.exp, not sure), with:

foreach_with_prefix print-object {"off" "off"} {
   gdb_test_no_output "set print object ${print-object}"

   ... ref printing tests ...
}

Could you do that please?

Thanks,
