--- Comment #6 from Martin Liška <marxin at gcc dot gnu.org> ---
So it's a different story and it's related to target options:

$ cat /home/marxin/Programming/testcases/pr80583-2.ii
struct S {
  __attribute__((__vector_size__(8 * sizeof(0)))) int a;
};

int __attribute__((target("avx"))) foo() {
  S *b{};
  __attribute__((__vector_size__(8 * sizeof(0)))) int x = b->a;
}

$ g++ /home/marxin/Programming/testcases/pr80583-2.ii -c
during RTL pass: expand
/home/marxin/Programming/testcases/pr80583-2.ii: In function ‘int foo()’:

Which ICEs for all releases I have (4.5.0+).
