Firefox fails on nested closures at 16 layers

How deep do you think you can nest your closures in JavaScript? Yes, we know there is no tail-recursion, probably no inlining either, we know we should not do this, but sometimes we still do. Before today I expected something like 64-128 levels of nesting to work out fine. In fact, Chrome chokes only at level 512 or so, due to stack overflow - fine.

EDIT: There is Bug #517781 reported 2009-09-20, and STILL NOT ADDRESSED. Please upvote it if you can.

But Firefox.. At level 16! Reference error: x16 is not defined
