+1 Fixing this specific bug would be good. Instinctively, I think we should build with -fno-strict-aliasing, so the compiler doesn't make the same mistake with similar code elsewhere in DPDK. I fear there is more than this instance. I also wonder if -Wstrict-aliasing could help us instead, if we don't want -fno-strict-aliasing.
