opal-runtime seems to break Chai assertion on arrays about opal-node-runtime

[ggrossetie]

Hello Sylvain,

I think it's related to asciidoctor/asciidoctor.js#299 and chaijs/chai#1109
In short, Opal uses circular references and when you use deep equals, Chai will loop indefinitely.

Thank you for your replay Guillaume.

I investigate the issue a little bit more after my initial message. Apparently, after having done some tests, Chai does not break on circular references. And I follow the code on the debugger, and it does not seem to be stuck in an infinite loop.

However, I notice opal is attaching something like 800 methods to the Array and Function prototypes (or maybe just to Object?)--and a deep inspection could result in a combinatory explosion.

I assume there is no easy way to reduce the Opal footprint on the standard objects prototypes?

Indeed definitely the same issue as chaijs/chai#1109

The next version of Opal will fix this issue: opal/opal#1821

I believe this issue was fixed in https://github.com/Mogztter/opal-node-runtime/releases/tag/v1.0.7
Could you please give it a try (an reopen this issue if it's not the case) ?
