Allocated ZSTs are immediately dropped

[kstrafe]

ZSTs should not be dropped as we may depend on their side-effects. Bumpalo does not drop ZSTs. If we add data to the type it is also not dropped.

use allocator_api2::alloc::Global;

type Bump = bump_scope::Bump<Global, 1, false>;
// type Bump = bumpalo::Bump;

#[test]
fn mytest() {
    struct DropEmit;
    impl Drop for DropEmit {
        fn drop(&mut self) {
            println!("=== DROPEMIT DROPPED === SHOULD NOT HAPPEN");
        }
    }

    let store = Bump::new();
    println!("Allocating");
    let dropemit = store.alloc(DropEmit);
    println!("Right after allocation");
    dropemit.into_raw();
}

Thanks for filing this issue.

This is now fixed in version 0.1.6!
