[Bug tree-optimization/17661] New: ICE in create_tmp_var

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

struct C
{
  int *c;
  C () : c (0) { }
  C (const C &x) : c (x.c) { }
  C &operator++ () { return *this; }
};

int
foo (void)
{
  int i = 0;
  C j;
  bool k = false;

  for (; i < 30; k ? j : ++j)
    k = false, ++i;

  return 0;
}

ICEs at any optimization level in create_tmp_var.
Works ok in G++ 3.4.2.
