Running under gdb, I see:

There's a thinko in this code:

      /* Find the next batch of constructors/destructors with the same
         initialization priority.  */
      for (;i < j; i++)
        {
          tree call;
          fn = VEC_index (tree, cdtors, i);
          call = build_call_expr (fn, 0);
          if (ctor_p)
            DECL_STATIC_CONSTRUCTOR (fn) = 0;
          else
            DECL_STATIC_DESTRUCTOR (fn) = 0;
          /* We do not want to optimize away pure/const calls here.
             When optimizing, these should be already removed, when not
             optimizing, we want user to be able to breakpoint in them.  */
          TREE_SIDE_EFFECTS (call) = 1;
          append_to_statement_list (call, &body);
        }
      while (i < len);
