  New Revision: 25631

  http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=rev&revision=25631

  Log:
    * cont.c (fiber_free): don't free unallocated local_storage. see #1325.
    
    * cont.c (cont_init): clear local_storage not to use current thread's.
    
    * cont.c (fiber_t_alloc, root_fiber_alloc): link itself always for
      a case that fiber_link_remove() is called before fiber_link_join().
    
    * cont.c (fiber_init): clear cont->vm_stack and th->stack before
      root_fiber_alloc() in rb_fiber_current().
