What steps will reproduce the problem?

abc = {};

(function() { typeof this["abc"] })();

What is the expected output? What do you see instead? not an error but i see:

TypeError: Object #<an Object> has no method 'abc' ... TypeError: Object #<an Object> has no method 'abc' at Object.<anonymous>...

What version of the product are you using? On what operating system? v8cgi 0.9 precompiled for windows on my windows xp it

Please provide any additional information below.

The described behavior is correct. Variables created without the "var" keyword are created in global scope (which is, by the way, a very bad practice), but the "this" keyword referes to module's exports object.
