Description of the problem:

Noticed a Stackoverflow question regarding the integer overflow functionality in --release -mode while compiling. See https://stackoverflow.com/questions/70776125/why-does-rust-perform-integer-overflow-checks-in-release

Suggested fix:

Adding a word "runtime" as a constraint:

When you’re compiling in release mode with the --release flag, Rust does not include runtime checks for integer overflow that cause panics.
