* compar.c (cmp_eq): returns 'false' if <=> returns 'nil'. * compar.c (cmp_gt,cmp_ge,cmp_lt,cmp_le,cmp_between): ditto. * pack.c (pack_pack): should propagate taintedness. * pack.c (pack_unpack): ditto. * eval.c (rb_thread_schedule): need to preserve errno before calling rb_trap_exec(). * regex.c (calculate_must_string): a bug in charset/charset_not parsing. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@2482 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
