ruby--ruby/ext/socket/socket.c
matz 88abd791f5 * parse.y (str_extend): shuould allow interpolation of $-x. 
* variable.c (rb_cvar_set): empty iv_tbl may cause infinite loop.

* variable.c (rb_cvar_get): ditto.

* variable.c (cvar_override_check): ditto.

* bignum.c (rb_big_eq): convert Bignum to Float, instead of
  reverse.

* time.c (time_localtime): getting tm should not be prohibited for
  frozen time objects.

* time.c (time_gmtime): ditto.

* version.c (Init_version): freeze RUBY_VERSION,
  RUBY_RELEASE_DATE, and RUBY_PLATFORM.

* file.c (Init_File): freeze File::SEPARATOR, ALT_SEPARATOR and
  PATH_SEPARATOR.

* file.c (rb_stat_cmp): should check operand type before calling
  get_stat().

* eval.c (rb_eval_cmd): should not invoke "call" with a block on
  any occasion.

* numeric.c (fix_aref): idx may be a Bignum.

* numeric.c (num_remainder): a bug in Numeric#remainder.

* eval.c (rb_exec_end_proc): END might be called within END
  block.

* class.c (rb_mod_clone): should not copy class name, since clone
  should remain anonymous.
