let me first address your curiosity, http://dpdk.org/dev/patchwork/patch/12993/( check the second comment) http://dpdk.org/ml/archives/dev/2016-June/042701.html 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.
