Original issue

Using latest rust-nightly, courtesy of rustup.sh. Including the full stacktrace below. I'd include the code that triggers this, but there's about 10 KLOC of it and I don't have a clue which part of it caused this. The code compiled just fine with rust-nightly - 201404300405~cbf1131~trusty built on 2014-04-30.

If there's any other info I can provide, please ask.

Do you have a link to the code that causes this? We're working on making a auto-reducer, and we're curious what happens to this!

[Valloric]

I wasn't quite ready to release the project now, but seeing how it now won't compile and an ICE is a serious bug, I'll try to push it out today.

[Valloric]

Here it is: https://github.com/Valloric/nailed

Run rustc parser.rs in top-level dir.

[Valloric]

Even easier, run rustc inlined_parser.rs. That also fails but inlined_parser.rs is a self-contained, generated file.

[erickt]

That stack trace looks very similar to #13645. It may be the same problem.

[alexcrichton]

Minimized:

#![crate_type = "lib"]

enum NodeContents<'a> {
    Children(Vec<Node<'a>>),
}

struct Node<'a> {
    contents: NodeContents<'a>,
}

impl<'a> Node<'a> {
    fn noName(contents: NodeContents<'a>) -> Node<'a> {
        Node{  contents: contents,}
    }
}

[Valloric]

Any progress on this one? I can't move forward on my project until this is fixed, it's a hard blocker.

[alexcrichton]

Closing as a dupe of #13853
