From 25ad722126c77a546ab1ac7111f090bd8d0e3c13 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=C3=86var=20Arnfj=C3=B6r=C3=B0=20Bjarmason?= Date: Thu, 21 Oct 2021 21:54:14 +0200 Subject: [PATCH] config.c: don't leak memory in handle_path_include() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fix a memory leak in the error() path in handle_path_include(), this allows us to run t1305-config-include.sh under SANITIZE=leak, previously 4 tests there would fail. This fixes up a leak in 9b25a0b52e0 (config: add include directive, 2012-02-06).
