[issue12928] exec not woking in unittest

[Ezio Melotti]

This doesn't seem related to unittest:

>>> class MyTest:
...     def test_a(self):
...         b = 1
...         exec(compile("a = b + 1", '', 'single'))
...         assert a == 2
... 
>>> t = MyTest()
>>> t.test_a()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 5, in test_a
NameError: global name 'a' is not defined

With unittest I get the same error.
