From 9e542f9a46a06247eafb5bc651fa06f3aaaad5eb Mon Sep 17 00:00:00 2001 From: "Miss Islington (bot)" <31488909+miss-islington@users.noreply.github.com> Date: Fri, 5 Jul 2024 08:59:06 +0200 Subject: [PATCH] [3.12] gh-121390: tracemalloc: Fix tracebacks memory leak (GH-121391) (#121393) gh-121390: tracemalloc: Fix tracebacks memory leak (GH-121391) The tracemalloc_tracebacks hash table has traceback keys and NULL values, but its destructors do not reflect this -- key_destroy_func is NULL while value_destroy_func is raw_free. Swap these to free the traceback keys instead.
