[New-bugs-announce] [issue15293] AST nodes do not support garbage collection

[Antoine Pitrou]

New submission from Antoine Pitrou <pitrou at free.fr>:

Add the following to test_ast:

diff --git a/Lib/test/test_ast.py b/Lib/test/test_ast.py
--- a/Lib/test/test_ast.py
+++ b/Lib/test/test_ast.py
@@ -199,6 +199,7 @@ class AST_Tests(unittest.TestCase):
         x.foobar = 42
         self.assertEqual(x.foobar, 42)
         self.assertEqual(x.__dict__["foobar"], 42)
+        x.x = x
 
         with self.assertRaises(AttributeError):
             x.vararg


and you'll get a reference leak.
