Adding that "true" only tells the Buffer module to skip the assert, which
is telling you about what is probably a legitimate problem. It looks like
on that platform ((undefined + 1) | 0) is ending up as NaN instead of 0.
Try adding proper initialization to the Base64Id constructor and see if
this fixes it:
var Base64Id = function() {
this.sequenceNumber = -1;
};
If so, that sounds like a V8 bug on that platform (should be simple to
reproduce on the console by executing "((undefined + 1) | 0)" and see if it
gets anything other than the integer 0).
