とりあえずの速報ですが，
test-all では下記のエラー：

test-ruby spec のほうでは

1)
String#% taints result for %s when argument is tainted ERROR
RuntimeError: can't modify frozen Float
/mnt/sdb1/ruby/trunk/spec/ruby spec/core/string/modulo_spec.rb:654:in
`taint'
/mnt/sdb1/ruby/trunk/spec/ruby spec/core/string/modulo_spec.rb:654:in
`block (2 levels) in <top (required)>'
/mnt/sdb1/ruby/trunk/spec/ruby spec/core/string/modulo_spec.rb:4:in
`<top (required)>'

というエラーが出ました．

とりあえず，テストを直せば良さそうだなぁと思っています．
