Downgrading to 16.0a1 (2012-06-05) fixes the problem.

Range between the two Nightlies:

I've attempted a backout of the main bug 659577 landing and the followup commit, but there are conflicts with things that landed after, so think it's perhaps just safer to leave for Luke to take a look at for now.
Comment 10 Luke Wagner [:luke] 2012-06-06 18:12:22 PDT
Yes, I'll look at it immediately.
Comment 11 Luke Wagner [:luke] 2012-06-07 01:18:13 PDT
Phew, I've tracked it down to a bug in the mjit changes: increment on a formal argument when formals are aliased by 'arguments' (but not by the scope chain) doesn't increment the canonical slot in the arguments object and so is effectively a nop.

Should be a simple fix; writing mjit patches isn't a good idea at this hour so I'll do it tomorrow.

Actually, the fix is pretty simple.

Verified fixed with the new Nightly - thanks! :-)
