Confirmed with current sources. Here's a mostly reduced testcase. Looks like something nasty 
between __inline__ and __builtin_extract_return_addr. Dies with -O or higher.

typedef unsigned _Unwind_Word __attribute__((__mode__(__word__)));
typedef unsigned _Unwind_Ptr __attribute__((__mode__(__pointer__)));

struct _Unwind_Context
{
  void *ra;
};

__inline__ _Unwind_Word
_Unwind_GetGR (struct _Unwind_Context *context, int index)
{
  int size;
  void *ptr;

  if (size == 1)
    return * (_Unwind_Ptr *) ptr;

  abort ();
}

__inline__ void *
_Unwind_GetPtr (struct _Unwind_Context *context, int index)
{
  return (void *)(_Unwind_Ptr) _Unwind_GetGR (context, index);
}

void
uw_update_context (struct _Unwind_Context *context)
{
  context->ra =__builtin_extract_return_addr (_Unwind_GetPtr (context, 2));
}
