Reduced testcase:
int  g();
struct string {
  static int _S_empty_rep_storage[];
  void  _M_destroy();
  char* _M_rep;
  ~string()
  {
if (_M_rep != (char*)_S_empty_rep_storage )
  if (g() = 0)
_M_destroy();
  }
};
extern void SDL_FreeSurface(int surface);
struct scoped_resource {
  ~scoped_resource()  {
SDL_FreeSurface(1);
  }
};
struct surface {
  scoped_resource surface_;
};
struct button {
  string help_text_;
  string label_;
  surface image_;
};
struct scrollbar {
  string help_text_;
  button uparrow_;
};
scrollbar a;

As far as I can tell PRE is adding mergephitmp on an edge to an abornal branch.
