            Bug ID: 102572
           Summary: ICE for skx in vect_build_gather_load_calls, at
                    tree-vect-stmts.c:2835
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: vsevolod.livinskij at frtk dot ru
  Target Milestone: ---

Reproducer:
int a, b, c, f;
void g(bool h, int d[][5]) {
  for (short i = f; i; i += 1) {
    a = h && d[0][i];
    for (int j = 0; j < 4; j += c)
      b = 0;
  }
}

Error:
