will see if can reproduce something off this info. first effort was to 
expand unittests:

         env1 = self.TestEnvironment(CPPDEFINES="SOME_DEFINE") 

         env2 = env1.Clone() 

         env2.Append(CPPDEFINES=["NO_SUCH_DEFINE"]) 

         self.assertEqual(list(env2.Dictionary('CPPDEFINES')), 
['SOME_DEFINE', 'NO_SUCH_DEFINE'])
         self.assertEqual(env1.Dictionary('CPPDEFINES'), "SOME_DEFINE")

that didn't fail...
