Summary: Computed hash is sometimes too large.
Initial Comment:
The current hash algorithm in dependency.rb (line 138) and specification.rb
(line 658) can sometimes create a hash that is too large. This is also possible
with Array#hash in MRI, which can also misbehave if one of the array elements
returns a large hash value:
class C
def hash
100000000000000000000
end
end
[C.new].hash # => in `hash': bignum too big to convert into
`long' (RangeError)
REXML has a similar issue. http://redmine.ruby-
lang.org/issues/show/1883 tracks the issue, and MRI will be
fixing the issue.
Suggested fixes are:

Hello,
I tried this patch, but I am still getting the error, at the same place in the
code. The error is the same with or without the patch to specification.rb;
dependency.rb was already like the patched part shown above. This happened
when installing using bundler, executed via capistrano.
We had been using hpricot, it wasn't needed, it was giving this error first.
I took it out, but then the same RangeError happened with mysql. I've seen it
before also with nokogiri. (Always with native gems, though).
Here's the relevant part of the log:

So, is this the same issue? It sure looks like it to me. I hope not to have to
dive into the innards of rubygems if possible. But we need to be able to
deploy. The app is working and passing tests on development, but hard to say
on staging as we can't get it over there with cap. I suppose it could all be
done by hand once anyway, but we (other dev on my team and I ) need to be able
to do this over again.
Thanks for your time in this!
Cheers,
Craig
