This example works with the current version of
rust v1.72.0 and current regex version v1.9.5

Run with:

	cargo run --release



By going beyond the bound of 40,000, rust will raise the
exception

   thread 'main' panicked at 'called `Result::unwrap()`
   on an `Err` value: CompiledTooBig(10485760)', main.rs:14:64
