This simple change makes object() works as expected for the short test case I tried:

                 /* Get the PMC instance and call the vtable method on that. */

This is the test:

.sub main :main
  $P0 = newclass ['myobj']
  addattribute $P0, 'name'
  $P1 = new $P0
  $P3 = new 'String'
  $P3 = 'world'
  setattribute $P1, 'name', $P3

.namespace ['myobj']

.sub hello :method
  print 'hello, '
  $P1 = getattribute self, 'name'
  say $P1

.sub 'invoke' :vtable
