munmap_chunk(): invalid pointer

[vOROn200]

where am I wrong? why do i get an error

use generator::Gn;

pub struct TestStruct<'a> {
    pub name: Cow<'a, str>,
    pub value: i32
}

impl<'a> TestStruct<'a>  {
    pub fn new() -> TestStruct<'a> {
        TestStruct { name: Cow::Owned("test".to_string()), value: 0 }
    }
}

pub fn test_1gen<'a> () -> impl Iterator<Item =TestStruct<'a>>
{
    Gn::new_scoped(move |mut s| {
        for _i in (0..10).step_by(2)
            {
                let py = TestStruct::new();
                s.yield_(py);
            }
        generator::done!();
    })
}

pub fn test_2gen<'a>() -> impl Iterator<Item = TestStruct<'a>> {
    let iter_test = test_1gen();

    Gn::new_scoped(move |mut s| {
        for i in iter_test
            {
                s.yield_(i);
            }
        generator::done!();
    })
}

fn main() {
    for i in test_2gen() {
        println!("{}", i.name);
    }
}

Thanks! This is apparently a bug. The root cause is that the done macro returns a dummy value and we should not run the drop on it. The fix is easy, just forget the dummy value.

just release 0.6.13 for the fix
