extern char *bar (const char *, const char *);
extern char *baz (char *, const char *);
extern unsigned int fn (const char *);
static const struct C { int i; } k = { 0};

struct S
{
  S (const C &x, unsigned int *y) : a (x), b (y) {}
  const C &a;
  unsigned int *b;
};

struct A
{
  ~A ();
  void helper (const S &);
};

struct B : private A
{
  B (const S &x)
  {
    helper (x);
  }
};

char *
foo (char *x, const char *y)
{
  unsigned int a;
  B b (S (k, &a));
  char *c = x;

  if (bar (y, "foo"))
    {
      baz (c, "foo");
      c += fn ("foo");
    }
  else if (bar (y, "bar"))
    {
      baz (c, "bar");
      c += fn ("bar");
    }

  return x;
}

causes ICE on powerpc-linux (32-bit).
