From a2f0da3af61455cdd86dc13bc305e50db58a5b08 Mon Sep 17 00:00:00 2001 From: Riccardo Mancini Date: Thu, 15 Jul 2021 18:07:12 +0200 Subject: [PATCH] perf test maps__merge_in: Fix memory leak of maps [ Upstream commit 244d1797c8c8e850b8de7992af713aa5c70d5650 ] ASan reports a memory leak when running: # perf test "65: maps__merge_in" This is the second and final patch addressing these memory leaks. This time, the problem is simply that the maps object is never destructed. This patch adds the missing maps__exit call.
