Subject: [PATCH] ref-filter: plug memory leak in reach_filter()
Date: Sat, 26 Sep 2020 10:37:29 +0200 [thread overview]
Message-ID: <d9922bbe-4e34-45fe-66a5-d7b5bf42117a@web.de> (raw)
21bf933928 (ref-filter: allow merged and no-merged filters, 2020-09-15)
added an early return to reach_filter(). Avoid leaking the memory of a
then unused array by postponing its allocation until we know we need it.
