* ext/socket/socket.c (sock_s_unpack_sockaddr_in): remove struct

  size check.  getnameinfo(3) can handle. [ruby-dev:19967]

* io.c (io_read): do not call rb_sys_fail() when required data
  length is zero. (ruby-bugs-ja PR#420)

* eval.c (umethod_proc): should raise TypeError, instead of
  returning error causing Proc.  Following the principle of "fail
  early".  [ruby-core:00927]

* pack.c (pack_pack): small but serious typo.

* eval.c (backtrace): skip internal allocator frame.
  (ruby-bugs-ja PR#416)
