[Bug target/26453] New: Segfault with -m64 -mtraceback=full

["amodra at bigpond dot net dot au" <gcc-bugzilla at gcc dot gnu dot org>]

The following segfaults in rs6000_output_function_epilogue when compiled with
-m64 -mtraceback=full.  r_o_f_e is being called via final_end_function in
rs6000_output_mi_thunk.  This is a regression from gcc-3.3.x.

class A1 {
public:
  virtual ~A1();
};
class A2 : public A1 { };
class A3 : virtual public A2 { };

class A4 : public A3 {
public:
  ~A4(void);
};
A4::~A4(void) {}
