static call to invalid vtable: VtableObject(VtableObject(object_ty=error::Error + 'static))

[JoelLarson]

Tried using the iron framework on Mac OS X Yosemite 10.10.1 with rustc 1.0.0-nightly (170c4399e 2015-01-14 00:41:55 +0000) and run into this issue. I have been trying to compile this with rust since 2015-01-12 version.

I'm not very knowledgable with the language itself or any systems programming languages, so if anything else is required for information, I'll reply ASAP.

Thanks!

extern crate iron;

use iron::prelude::*;
use iron::status;

fn main() {

  fn hello_world(_req: &mut Request) -> IronResult<Response> {
    Ok(Response::with((status::Ok, "Hello World!")))
  }

  let web_server = Iron::new(hello_world);

  web_server.listen("localhost:3000").unwrap();

  println!("On 3000");
}

I am not sure but this looks a lot like #20676 . There seems to be a fix in #21089. If you need it urgently you could try to built rust yourself from that version. Don't know about the timeline when it will be merged into rust

[JoelLarson]

Crap. I'd have not posted about this if search would have returned with that result. I agree that it is most likely the same problem. I will test it when I get some time and report back.

[tamird]

Looks like this was a dupe of #20676 which was fixed in #21089. @steveklabnik close?
