New submission from Yang Feng <charles...@foxmail.com>:
Seeing the following program, in the second assertRaises(), function
"test_invalid_adpcm_state()" is recursively called. Then a fatal Python error
shows up and the Python interpreter crashes.
++++++++++++++++++++++++++++++++++++++
import unittest
import audioop
class TestAudioop(unittest.TestCase):
pass
def test_invalid_adpcm_state():
TestAudioop.assertRaises(TypeError, audioop.lin2adpcm, b'\x00', 1, 555)
TestAudioop.assertRaises(test_invalid_adpcm_state(),
audioop.adpcm2lin, b'\x00', 1, (0, (- 1)))
TestAudioop = TestAudioop()
test_invalid_adpcm_state()
