[ruby-core:53931] Re: [ruby-trunk - Bug #8204] ObjectSpace.each_object(Bignum) can generate Bignums that are to small to be Bignums
From:

ruby-core #53931
Note that you can obtain whichever Bignum you want using coerce. For example: x = (1 << 100).coerce(42).first # => 42 x.class # => Bignum I saw that used in test/* I never bothered to investigate it, but I'm pretty sure this could lead to multiple bugs as MRI assumes that Bignum means big number in many places.
