Crash test 

The browser crashes when the following function is run:

Function.prototype.call.apply(fn, arguments)

where fn is any function, and the arguments object has at least 3 items.

I have experienced this only in recent nightly builds, using Mac OS X 10.5.8. The crash doesn't happen while the script debugger is on, or when it is run from the location bar, or when fn has been successfully called before.
