Berker Peksag added the comment:
What do you mean by crash? I think the purpose of the test is to crash the
interpreter:
def test_recursionlimit_fatalerror(self):
# A fatal error occurs if a second recursion limit is hit when
recovering
# from a first one.
...
self.assertIn(
b"Fatal Python error: Cannot recover from stack overflow",
err)
test_sys passes for me in Python 3.5, but not in Python 3.6:
======================================================================
