I don't think that's a valid comparison. The behavior does differ when it comes to cleanly releasing resources. Rust's panic performs the drop actions for the current values on the stack, a SIGILL or SIGSEGV crash doesn't.

#[derive(Debug)]
struct MyStruct {}

impl Drop for MyStruct {
	fn drop(&mut self) {
		println!("{:?}", "imagine cleanup here"); // this is called
	}
}

fn main() {
	let a = MyStruct {};
	panic!("panic!");
        println!("{a:?}");
}

Try it yourself
