forcing a garbage collection:
  walking the live PyGccWrapper objects
    marking inner object for: gcc.IntegerCst(42)
    marking inner object for: gcc.StringCst('I am only referenced via a python wrapper')
  finished walking the live PyGccWrapper objects
completed the forced garbage collection
verifying that the underlying GCC objects were marked
all of the underlying GCC objects were indeed marked
