On the default branch, if you run test_ast in a loop: ./python -E -m test -F test_ast you will see that the process memory use grows very quickly. This doesn't happen on 3.2. I'm not a Valgrind expert so perhaps someone else can take a look. Otherwise I'll try to bisect. |

So, the culprit is: changeset: 75542:3877bf2e3235 user: Benjamin Peterson <benjamin@python.org> date: Mon Mar 12 09:46:44 2012 -0700 summary: give the AST class a __dict__ |

Strangely, the reference leak was fixed in: changeset: 75686:9e7f6ddc0d76 user: Benjamin Peterson <benjamin@python.org> date: Wed Mar 14 21:50:29 2012 -0500 summary: free AST's dict But it didn't fix the memory leak. |
