Target version: 1.9.2
ruby -v: ruby 1.9.2p180 (2011-02-18 revision 30909) [x86_64-darwin11.0.0]


Tested on 1.9.2-head, 1.9.2-p0 and 1.9.2-p180. 

If I run this:
<code>
ruby -e '(0..255).zip(0..255)' 
</code>

I get this:

But if I do:

<code>
ruby -e '((0..255).to_a).zip(0..255)'
</code>

it works ok.
