As in the title, the one I've noticed is error messages referencing a Vec<i32> often prints as a Vec<i22>.

Screenshot below:

Steps to reproduce:

In this case, create an immutable Vec<i32> and try to borrow it (I used the "assign cookies" challenge, but suspect any challenge and any error involving Vec<i32>will do).

I've also noticed some weirdness with cmp::max sometimes returning <0 when passed (0, some_number). Will file separately.
