[Rails] -517611318:Fixnum ... WTF?

[Kyle Maxwell]

I'm getting occasional errors that look like:

Some method called for -517611318:Fixnum

The method is constantly changing, and this error happens on ~5% of
the page loads on my Mac Tiger development box.  It's happening on
Ruby 1.8.2, and 1.8.4 compiled from source.  I haven't seen it on my
Linux production boxes.  I was wondering if anyone had seen this
before?
