From 367ea893847439502e155708539917bf655beb40 Mon Sep 17 00:00:00 2001 From: "Miss Islington (bot)" <31488909+miss-islington@users.noreply.github.com> Date: Mon, 16 Dec 2024 22:26:39 +0100 Subject: [PATCH] [3.13] Free arena on _PyCompile_AstOptimize failure in Py_CompileStringObject (GH-128006) Free arena on _PyCompile_AstOptimize failure in Py_CompileStringObject (GH-127910) After commit 10a91d7e9 introduced arena cleanup, commit 2dfbd4f36 removed the free call when _PyCompile_AstOptimize fails.
