 | >Description:
 | Hi,
 | 
 | I experiment a problem with using rust Library which use lib kqueue. This library (https://github.com/carllerche/mio) fails with an assertion eror about EV_ERROR kqueue constant.
 | 
 | The error occurs at line 118 of this file https://github.com/carllerche/mio/blob/master/src/sys/unix/kqueue.rs .
 | 
 | I reproduce for convenience the related assert test here:
 | 
 | debug_assert_eq!(change.flags & libc::EV_ERROR, libc::EV_ERROR); 
 | 
 | I tried in FreeBSD the same library and I don't get this error.
 | 
 | Could you please help me with your point of vue about this behaviour ?
 | 
 | is this behaviour seems to you expected in Net BSD ?
 | 
 | I made an issue report on github repo of a lib using mio:
 | https://github.com/hyperium/hyper/issues/1435
 | 
 | >How-To-Repeat:
 | You could reproduce this with:
 | installing rust from official site:
 | curl https://sh.rustup.rs -sSf | sh
 | 
 | then you could test this code here:
 | https://hyper.rs/guides/server/hello-world/
 
 Works in current and I think it will also work in 8. Can you please try that?

Ok, the NetBSD in that I tried this code is my usual working machine, but I will try on a VM ASAP.

Do you know why this code fails on the stable version? (a link to a PR by example)

Thanks for your reply(, and sorry for the typing error on uname.)
