From dfba071ddc3e609e61770b34ab0115fbce05edb2 Mon Sep 17 00:00:00 2001 From: Eugene Uriev Date: Sun, 31 Mar 2024 23:03:20 +0300 Subject: [PATCH] mcheck: Use memset/memcpy instead of MALLOC_ZERO/MALLOC_COPY for mcheck. These fast helpers sometimes breach mem-chunk boundaries. Thus they trigger mcheck alarm. Standard ones are accurate though.
