Created by: cmichi

Closes #163 (closed).

Output currently looks like this:

This typically goes back to a known bug in the Rust compiler:

As a workaround try to insert `overflow-checks = false` into your `Cargo.toml`. 
This will disable safe math operations, but unfortunately we are currently not  
aware of a better workaround until the bug in the compiler is fixed.
