[Bug tree-optimization/27144] [4.2 regression] segfault with -O2 on x86_64

["pinskia at gcc dot gnu dot org" <gcc-bugzilla@gcc.gnu.org>]

------- Comment #3 from pinskia at gcc dot gnu dot org  2006-04-13 17:01 -------
Confirmed, here is a slightly reduced testcase:
typedef struct {unsigned *p; }
hvl_t;
test_vltypes_compound_vlen_vlen (void) {
  typedef struct {
    int i;
    float f;
    hvl_t v;
  }
  s1;
  s1 wdata[128];
  unsigned i, j, k;
  hvl_t *t1, *t2;
  for (i = 0; i < 128; i++)
  {
      wdata[i].i = i * 10;
      wdata[i].f = (float) ((i * 20) / 3.0);
      wdata[i].v.p = malloc ((i + 16) * sizeof (hvl_t));
      for (t1 = (wdata[i].v).p, j = 0; j < (i + 16); j++, t1++)
      {
          for (k = 0; k < j + 8; k++)
            t1->p[k] = i * 100 + j * 10 + k;
        }
    }
}
