Subject: [PATCH 07/11] merge-file: fix memory leaks on error path
Date: Thu, 30 Jun 2022 20:00:17 +0200 [thread overview]
Message-ID: <patch-07.11-8803a0df799-20220630T175714Z-avarab@gmail.com> (raw)
In-Reply-To: <cover-00.11-00000000000-20220630T175714Z-avarab@gmail.com>
Fix a memory leak in "merge-file", we need to loop over the "mmfs"
array and free() what we've got so far when we error out. As a result
we can mark a test as passing with SANITIZE=leak using
"TEST_PASSES_SANITIZE_LEAK=true".
