let me first address your curiosity,

Ferruh,
I have tested on a x86 machine with gcc 6.1. I could n't see any issues
with i686-native-linuxapp-gcc target
Steps following to create gcc 6.1 toolchain
https://sahas.ra.naman.ms/2016/05/31/building-gcc6-1-on-fedora-23/
(removed --disable-multilib to have support for -m32)
➜ [dpdk-master] $ gcc -v
Using built-in specs.
COLLECT_GCC=gcc
COLLECT_LTO_WRAPPER=/opt/gcc-6.1.0/libexec/gcc/x86_64-pc-linux-gnu/6.1.0/lto-wrapper
Target: x86_64-pc-linux-gnu
Configured with: ../gcc-6.1.0/configure --prefix=/opt/gcc-6.1.0
--enable-languages=c,c++ --enable-libmudflap --with-system-zlib
Thread model: posix
gcc version 6.1.0 (GCC)
More over this issue seems like an issue from x86 rte_memcpy implementation.
Jerin
