Subject: * string.c (RESIZE_CAPA): check string attribute before modifying  
 capacity member of string structure.  [ruby-dev:24594]

* ext/zlib/zlib.c (gzreader_gets): use memchr() to to gain
  performance.  [ruby-talk:117701]

* sprintf.c (rb_f_sprintf): raise ArgumentError for extra
  arguments, unless (digit)$ style used.

* ext/zlib/zlib.c (gzreader_gets): use memchr() to to gain
  performance.  [ruby-talk:117701]

* sprintf.c (rb_f_sprintf): raise ArgumentError for extra
  arguments, unless (digit)$ style used.

* eval.c (frame_free): Guy Decoux solved the leak problem.
  Thanks.  [ruby-core:03549]

* ext/zlib/zlib.c (zstream_append_input): clear klass for z->input
  to avoid potential vulnerability.
