The following valid code snippet triggers an ICE on mainline and 4.3 branch
when compiled with "-ftrapv -O3":

================================
void foo(int x[])
{
  int i, j;

  for (i = 0; i < 2; i++)
    for (j = 0; j < 2; j++)
    {
      x[i] = x[i*j];
      x[i] = x[i*j];
    }
}
================================

bug.c: In function 'foo':
bug.c:2: internal compiler error: tree check: expected integer_cst, have
polynomial_chrec in int_cst_value, at tree.c:7968
Please submit a full bug report, [etc.]
