From: Alexander Kuleshov Date: Wed, 13 Jan 2016 11:57:35 GMT Subject: [PATCH] Makefile: describe XMALLOC_POISON Message-ID: <1452686255-8757-1-git-send-email-kuleshovmail@gmail.com> The do_xmalloc() functions may fill an allocated buffer with the known value (0xA5) for debugging if we will pass the XMALLOC_POISON option during build. This patch adds description of this option to the Makefile.
