[Bug tree-optimization/35006] [4.3 Regression] Segfault in remove_unused_locals

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

------- Comment #3 from pinskia at gcc dot gnu dot org  2008-01-29 00:48 -------
Here is a reduced testcase:
typedef unsigned long grub_uint64_t;
typedef grub_uint64_t grub_size_t;
grub_cmdline_get (
unsigned max_len,
    int echo_char
)
{
  unsigned xpos, ypos, ystart;
  grub_size_t lpos, llen;
  char buf[max_len];
  void cl_print (int pos, int c)
  {
      char *p;
      for (p = buf + pos; *p; p++)
      {
        if (xpos++ > 78)
          grub_putchar ('\n');
        grub_putchar (*p);
      }
 }
 void cl_delete (unsigned len)
 {
   cl_set_pos ();
   cl_print (lpos, ' ');
   grub_memmove ();
   cl_print (lpos, echo_char);
   cl_set_pos ();
 }
 cl_delete (llen);
 grub_size_t n = lpos;
 cl_delete (n);
}

---- CUT ----
Adding -fdump-tree-all, the ICE goes away.
