Though there appears to be a bug. Somewhere in between, the 64-bit integers are being transitioned through an NV (double) before being converted back to integers for the iterator it seems:

There is code that assumes NV vars can handle larger integers than IV and UV vars can. That's not the case for all builds anymore, so these builds have unexpected overflow conditions.

(BrowserUK probably knows that, but I thought someone else might be curious.)
