Wrong chapter was specified

[enox3]

I found a bug, where the wrong chapter was specified, the link led to chapter 18, but the text stated it was chapter 17.

It seems that the same issue occurs later in the text as well and hasn't been addressed. Specifically:

Boxes provide only the indirection and heap allocation; they don’t have any other special capabilities, like those we’ll see with the other smart pointer types. They also don’t have the performance overhead that these special capabilities incur, so they can be useful in cases like the cons list where the indirection is the only feature we need. We’ll look at more use cases for boxes in Chapter 17, too.

Would this issue include the listings being mislabeled, or should another issue be raised for that?

For example, looking at the first code block of chapter 18.1 it's listed as "Listing 17-1" when it should be "Listing 18-1". In chapter 17.6 the text also states "Listing 17-TODO" which seems like it should be "Listing 17-42".
