STINNER Victor added the comment:
The leak can reproduce only using this test:
def test_execve_invalid_env(self):
args = [sys.executable, '-c', 'pass']
# equal character in the enviroment variable name
newenv = os.environ.copy()
newenv["FRUIT=ORANGE"] = "lemon"
with self.assertRaises(ValueError):
os.execve(args[0], args, newenv)
It seems like the bug is in parse_envlist() function of Modules/posixmodule.c,
when a key contains the '=' character.
