Upstream bug is at https://bugs.dpdk.org/show_bug.cgi?id=97#c18
(Can't link it here :-/ )
They say:
- No crash seen with code generated by clang-6 or gcc-6, probably because they
do not generate AVX512 instructions.
- Crash is confirmed with gcc-7 and gcc-8 when using AVX2 version of rte_memcpy.
Nobody tested the one in Disco yet, and I have no repro yet for my own.
Note: Really worth to read through all the info in that bug.
** Also affects: dpdk
