@reem do you know which version of rustc you were running on when this happened?

For example, my rustc -v output is:

rust$ rustc -v
rustc 0.12.0-pre (c95aa9950 2014-09-04 03:01:03 +0000)

This code compiles and works for me.

rust$ rustc --test ../scratch/17021.rs
rust$ ../scratch/17021

running 1 test
test test_works ... ok

test result: ok. 1 passed; 0 failed; 0 ignored; 0 measured

Appears to work fine now, must have been fixed by some change in the last few days. Thanks for investigating!

Sure!

Weird thing is, this is still failing Travis. On my phone, so no link, but the most recent build for that repo shows the same ICE.
Thanks,

Travis nightlies trail slightly behind the latest builds. Some ideas have gotten passed around about improving that rate: see #16649 for details.

This code used to produce the following ICE: error: internal compiler error: get_unique_type_id_of_type() - unexpected type: closure, ty_unboxed_closure(syntax::ast::DefId{krate: 0u32, node: 66u32}, ReScope(63u32)) This is a regression test for issue rust-lang#17021.

rozaliev · 2014-09-08T12:54:50Z

It's still reproducible with
rustc 0.12.0-pre-nightly (aaf141d 2014-09-07 23:01:34 +0000)

I can reproduce this, too, but only with the -g flag on (which cargo build & cargo test set):

If I drop -g, it builds fine:

Reproducible on rustc 0.12.0-pre-nightly (09abbbdaf 2014-09-11 00:05:41 +0000).

@huonw would you reopen this, please?

nathantypanski · 2014-09-11T21:34:30Z

I'm really curious why/how #17093 passes the build if all of these are failing. I'll try bisecting from the c95aa99 build using this code:

#![feature(unboxed_closures, unboxed_closure_sugar)]

fn bug() {
  let c = box |&:| {};
}

(both this and the OP's code compile on c95aa99, for reference)

tomassedovic · 2014-09-11T21:52:59Z

@nathantypanski is #17093 being compiled with the -g flag? I'm getting the ICE only with -g on.

nathantypanski · 2014-09-11T23:16:23Z

@tomassedovic thanks, it breaks with -g for me. I should have read that more carefully.

Anywho, I'll try to look into it. Maybe someone more experienced than me will solve it first, though.

This catches two unhandled patterns in middle/trans/debuginfo.rs where a ty::ty_unboxed_closure could show up, preventing various potential ICEs when #[feature(unboxed_closures)] is used with `-g`. It also updates the test case from rust-lang#17093 in response to new information from rust-lang#17021 showing that the test still caused an ICE when compiling with debuginfo. Closes rust-lang#17021.

dckc · 2014-09-17T03:31:51Z

I'm also seeing this problem with:

rustc 0.12.0-nightly (d7e1bb5ff 2014-09-21 01:00:29 +0000)

…as described in #17454. A code snippet is attached to that issue, but it's basically the same code that everybody else is having problems with.

I can confirm that the code builds with cargo build:

Could not compile `replace-map`.

This is falling through a wildcard match clause in debug_info.rs:

        match ty::get(type_).sty {
            ty::ty_nil      |
            ty::ty_bot      |
            ty::ty_bool     |
(...snipped...)
            _ => {
                cx.sess().bug(format!("get_unique_type_id_of_type() - unexpected type: {}, {:?}",
                                      ppaux::ty_to_string(cx.tcx(), type_).as_slice(),
                                      ty::get(type_).sty).as_slice())
            }
        };

This is probably a relatively easy fix—it's generating some sort of unique representation for each type.

@emk you can see my attempt at fixing that here
nathantypanski@8861e1d

It didn't work, for reasons that are unknown to me. But, hey, it adds to that pattern match like you suggest.

Getting the same error with

#![feature(unboxed_closures)]
#![feature(unboxed_closure_sugar)]

fn main() {
    let b = 3u;
    let a = |:| b;
}

|&:| and |&mut| result in the same error.

Taking a look

This fixes an ICE. Closes issue rust-lang#17021

This causes it to hit the previously ICEing debuginfo codepath

This closes issue #17021.

dckc · 2014-10-14T06:15:46Z

my symptoms above (#17021 (comment)) seem to have subsided as of rustc 0.13.0-nightly (adb44f5 2014-10-12 00:07:15 +0000)

tomassedovic · 2014-10-14T06:36:26Z

Yep, #17803 did it for me. We can close this.

…ykril Support hovering limits for adts Fix rust-lang#17009 1. Currently, r-a supports limiting the number of struct fields displayed when hovering. This PR extends it to support enum variants and union fields. Since the display of these three (ADTs) is similar, this PR extends 'hover_show_structFields' to 'hover_show_adtFieldsOrVariants'. 2. This PR also resolved the problem that the layout of ADT was not restricted by display limitations when hovering on the Self type. 3. Additionally, this PR changes the default value of display limitations to `10` (instead of the original `null`), which helps users discover this feature.
