Attempted to assign to readonly property

[onury]

I dropped Q and started to use Bluebird in my Titanium app. But when I build for iOS, I get the following error described.

function Promise(executor) {
    this._bitField = 0; // <---- this line throws

Appcelerator does not output a trace for this error but app crashes and error dialog shown in the app reads: Attempted to assign to readonly property at bluebird.js line 2697.

Bluebird version 3.3.5 (latest) (development and production tested both)
Titanium SDK version 5.2.2.GA (latest)
Node version 4.3.0

Doesn't seem to be specific to bluebird, there is nothing that would make it readonly
