I found wrong hash value for hash of hash in 1.9.1

In ruby 1.8.6 (2007-09-24 patchlevel 111) [i686-linux]
irb(main):001:0> h = {}
=> {}
irb(main):002:0> h[1]=2
=> 2
irb(main):003:0> h[h]=3
=> 3
irb(main):004:0> h
=> {1=>2, {...}=>3}
irb(main):005:0> h[h]
=> 3
irb(main):006:0> h[h]=4
=> 4
irb(main):007:0> h
