The problem disappears if I add a gc.collect() loop at the beginning of the new test:

diff --git a/Lib/test/test_exceptions.py b/Lib/test/test_exceptions.py
index 79798ecf05..e0aeac9d10 100644
--- a/Lib/test/test_exceptions.py
+++ b/Lib/test/test_exceptions.py
@@ -1014,6 +1014,7 @@ def cycle():
 
     def test_no_hang_on_context_chain_cycle2(self):
         # See issue 25782. Cycle at head of context chain.
+        while gc.collect(): pass
 
         class A(Exception):
             pass
