From b1425be92a300456f5b779869a0535944ca59fce Mon Sep 17 00:00:00 2001 From: pfg Date: Thu, 30 Jul 2015 14:31:09 +0000 Subject: GCC: Add a new option "-fstack-protector-strong" This includes additional functions to be protected: those that have local array definitions, or have references to local frame addresses. This is a new option in GCC-4.9 that was relicensed by Han Shen from Google under GPLv2 for OpenBSD.
