Subject: * array.c (rb_ary_delete): element comparison might change array  
 size. [ruby-dev:24273]

* parse.y: make ruby parser reentrant. merge ripper parser to the
  real one.  this change makes ruby require bison.

* file.c (rb_file_truncate): clear stdio buffer before truncating
  the file.  [ruby-dev:24191]

* ext/digest/digest.c: use rb_obj_class() instead of CLASS_OF
  which might return singleton class.  [ruby-dev:24202]
