On older CPUs it will crash with # /usr/local/bin/cjdroute=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20= =20=20=20=20=20=20=20=20 Illegal instruction Disassembly: (gdb) disass 0x000000000022ca47,+60=20=20=20=20=20=20=20=20=20=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20= =20=20=20=20=20=20=20 Dump of assembler code from 0x22ca47 to 0x22ca83: =3D> 0x000000000022ca47: vxorps %xmm0,%xmm0,%xmm0 0x000000000022ca4b: vmovaps %ymm0,(%rsp) =E2=80=A6 --=20 You are receiving this mail because: You are the assignee for the bug.=
