Hello attached test produces ICE, when compiled as
$ gcc -S -O3 1.c -mavx2
It seems that full unroll or copyprop (or whatever) introduces something wrong.
1.c: In function 'more_xrv':
1.c:23:1: error: type mismatch in pointer plus expression
more_xrv(void)

vect_vec_iv_.15_88 = vect_cst_.13_60 + { 64B, 64B, 64B, 64B };
