I think it has something todo with JavaScript engine. Different engine treats parseInt('045') differently.
Alfreso use Rhino as JavaScript engine,using Rhino to evalute parseInt('045') will give you 37.

Because Octal numbers were removed by ES 5 (ECMA Script version 5) http://www.ecma-international.org/ecma-262/5.1/

Rhino has been fixed to not have octal numbers, I guess its just a case of waiting for the browsers to catch up. You may also be able to set your browser to "strict mode" to get a more standard compliant script engine.

Edit - hang on - the answer is wrong they should all be 45. However parseInt of octal numbrs is deprecated, clearly there's a bug somwerhere.
