  Yeah, I am seeing the same. 64-bit issue, it looks like.

  This is actually due to failing spec/core/bignum/bignum_spec.rb:

  2**30 has Fixnum class (not Bignum) and gets dumped as such.

  Well, MRI seems to also fail on this one.

  On 64-bit MRI's threshold between Fixnum and Bignum is not 2**29, but 2**62:

  irb(main):013:0> (2**62).class
  => Bignum
  irb(main):014:0> (-1+2**62).class
  => Fixnum
  

  (that's MRI's irb)

  And here's rubinius:

  irb(main):002:0> (2**30).class
  => Fixnum
  irb(main):003:0> (2**31).class
  => Bignum

  ./bin/ci passes for 64 bit as of 1a8c9966fa...

  Fixnum is now also MRI compatible on 64 bit
