I tried this code (playground):

struct Bomb;

impl Drop for Bomb {
    fn drop(&mut self) {
        let _bomb = Bomb;
        panic!()
    }
}

fn main() {
    drop(Bomb);
}

I expected to see this happen: A double panic/panic in dtor causes the program to abort

Instead, this happened: The program never terminates and instead continues printing so many backtraces
