--- Comment #12 from Mikael Slevinsky ---
It is fixed for all GCC versions I checked: all the up-to-date versions of 4.9,
5, 6, 7, 8, 9 from Homebrew.
Also, I recently updated from High Sierra to Mojave, and the new clang is:

I can confirm this is fixed, thank you!
P.S. the exact processor type is a Xeon(R) W-2191B CPU @ 2.30GHz.

I'm not sure if this answers your question, but compiling the same program
(modifying 8 to 128 to tease the compiler into using zmm registers) with
clang-6 works fine.

I'm not so sure. Consider the following minimal test file:
#include
#include
int main(void) {
double * X, * Y, * Z;
X = (double *) calloc(8, sizeof(double));
Y = (double *) call
