This is the code in question, with line 3380 the last one:

  void
  mark_backtrace (void)
  {
    register struct backtrace *backlist;
    ptrdiff_t i;

    for (backlist = backtrace_list; backlist; backlist = backlist->next)
      {
	mark_object (*backlist->function);

Shouldn't it be

	mark_object (backlist->function);

instead?
