Weird, why g++ can do the task although probably less efficiently than icc?
$ g++ -O3 -march=core-avx-i -mtune=core-avx-i -mavx2 stream.c ; objdump -d
a.out | grep ymm
stream.c:106:48: warning

Hmm, I cannot due to ABI incopmpatibility.
However, the other reported also showe 5.2.1 was affected as well.

I am on Gentoo Linux but 5.4.0 is nevertheless still unavailable for general

I will try to reproduce this
