Strange, with the 4.7-RH cc1plus I can reproduce the segfault even on
inline void *operator new (__SIZE_TYPE__, void *p) throw ()
{
  return p;
}
struct B
{
  virtual ~B ();
  B ();
};
struct A : B
{
  A () : B () {}
  virtual void bar ();
};
void
foo ()
{
  char a[64];
  B *b = new (&a) A ();
  b->~B ();
}

(at -O2, both -m32 and -m64), but I can't reproduce it with a cross from
x86_64-linux to powerpc64-linux.
