The sentences were not affirmative because I didn't confirm the intention of the author as of the above message. But with his private mail, I could do after that. The patch actually does not break the case GC_LISP_OBJECT_ALIGNMENT < sizeof Lisp_Object, but fixes it when the stack grows in the decreasing direction.
