    * eval.c (rb_frame_last_func): return the most recent frame method
      name.
    
    * thread.c (recursive_list_access): use the last method name,
      instead of the current method name which can be unset in some
      cases, not to use a symbol by the invalid ID.
      [ruby-core:66742] [Bug #10579]
    
    * thread.c (exec_recursive): use the same last method name as
      recursive_push in the error message when recursive_pop failed.
