            Bug ID: 62075
           Summary: [4.8/4.9/4.10 Regression] Vectorizer ICE on dolphin
           Product: gcc
           Version: 4.9.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jakub at gcc dot gnu.org

int a[16][2];
struct A
{
  int b[16][2];
  int c[16][1];
};

void
foo (struct A *x)
{
  int i;
  for (i = 0; i < 16; ++i)
    {
      x->b[i][0] = a[i][0];
      x->c[i][0] = 0 != a[i][0];
      x->b[i][1] = a[i][1];
    }
}

ICEs at -O3, starting with r180057 (before that we wouldn't attempt to
vectorize it):
