From b8330672336994336526bfc8ac118b30eaaacd73 Mon Sep 17 00:00:00 2001 From: Ricardo Salveti Date: Thu, 16 Aug 2018 20:11:07 -0300 Subject: mozjs: disable null pointer optimization with GCC >= 6 Mozjs fails to start on several architectures due broken build optimizations when built with GCC >= 6. Set -fno-tree-vrp -fno-strict-aliasing -fno-delete-null-pointer-checks to both CFLAGS and CXXFLAGS as workaround (flags also used by Firefox and Fedora).
