Same issue for ::jsstack -vn0

32 bits

I noticed that some functions' position have the value (2^31)-1. Here's an extract from ::jsfunctions' output.

fe93f929        1 <anonymous> (as <anon>)                  util.js position 2147483647
fe93e60d        1 <anonymous> (as <anon>)                  assert.js position 2147483647
fe93c4e5        1 <anonymous> (as <anon>)                  buffer.js position 2147483647

So far, all the functions I've seen with a position of (2^31)-1 are anonymous functions.
