Confirmed.

The following testcase crashes the mainline compiler (-O -march=pentium4):

=========================================
struct A
{
  struct A* p;
};

int bar(struct A*, struct A*);
int baz();

void foo (int i, struct A* q)
{
  char c, d = 1;

  while (i)
    {
      if (q)
        c = 1;
      if (q->p->p)
        d = 0;
      if (bar (q->p->p, q->p))
        c = 0;
      --i;
    }

  if (c && d && baz ())
    return;
}
=========================================
