--- Comment #1 from Martin Liška <marxin at gcc dot gnu.org> ---
Confirmed, all releases I have ICE.
(gdb) p debug_rtx(val)
(mem/c:V32QI (plus:DI (reg/f:DI 82 virtual-stack-vars)
(const_int -32 [0xffffffffffffffe0])) [0 x+0 S32 A256])
$4 = void
(gdb) p mode
$5 = BLKmode
Problem is probably that nehalem does not have -mavx2 enabled and it's enabled
in the source code via target attribute.
