The following simplified testcase still crashes on mainline when compiled
with "-O2":

==============================
struct A
{
  int i, *p;
  A* a;

  void foo()
  {
    if (p)
      p++;
    else
    {
      if (i)
        i = 1;
      i++;
    }
  }

  A();
};

A::A()
{
  int j;
  A* q;

  while (j)
  {
    j--;
    while (j--)
    {
      q = this;
      a->foo();
      a->foo();
    }

    q->a++;
    a->foo();
    a->foo();
  }

  A b;
}
==============================
