--- Comment #1 from Martin Liška <marxin at gcc dot gnu.org> ---
Confirmed, started with r10-6809-g7f5617b00445dcc8.
I can reproduce that on Intel SDE simulator:
$ g++ pr94300.c -O1 -march=skylake-avx512 &&
/home/marxin/Programming/intel-sde-new/sde-external-8.16.0-2018-01-30-lin/sde
-skx -- ./a.out
Aborted (core dumped)
