reduced testcase
Output:
$ x86_64-pc-linux-gnu-gcc -O -mavx512f -masm=intel testcase.c
/tmp/cc6ywLFg.s: Assembler messages:
/tmp/cc6ywLFg.s:44: Error: operand size mismatch for `vinserti64x4'
$ grep vinserti64x4 testcase.s
vinserti64x4 zmm0, zmm3, ymm0, $0x0
The correct form would be:
vinserti64x4 zmm0, zmm3, ymm0, 0x0
gcc-6 produces correct assembly.
