ICE when linking to old libcore #14748

mvdnes · 2014-06-08T12:53:16Z

Description

I am writing an x86 kernel in rust for my own fun. I am using an myself-compiled libcore to use with this, as the host is x86_64 and I need an i386 lib. This is done with rustc -O --target=i386-unknown-linux ../rust/src/libcore/lib.rs. Sometimes (not always) when I update my host version of rust (using the thestinger Arch repo), I get an ICE. They differ each time, but the latest was:

rustc -L. -O --target i386-unknown-linux --crate-type lib -o main.o --emit obj main_x86.rs
error: internal compiler error: unexpected failure
note: the compiler hit an unexpected failure path. this is a bug.
note: we would appreciate a bug report: http://doc.rust-lang.org/complement-bugreport.html
note: run with `RUST_BACKTRACE=1` for a backtrace
task 'rustc' failed at 'assertion failed: start <= end', /build/rust-git/src/rust/src/libcore/slice.rs:540

This is resolved by updating the rust repo, and recompiling the libcore crate. Maybe the failure could give of a more useful error-message?

Could you provide a backtrace of the ICE as well?

@mvdnes Have you been able to reproduce this ICE recently?

mvdnes · 2015-02-15T10:41:51Z

Yes, not very often but two days ago I did. Steps to reproduce:

// hello.rs
#![feature(io)]
fn main() {
    println!("Hello, World!");
}

Next we download the compiler from 14 febuary and the libraries of 8.

wget http://static.rust-lang.org/dist/2015-02-14/rustc-nightly-x86_64-unknown-linux-gnu.tar.gz
tar -xf rustc-nightly-x86_64-unknown-linux-gnu.tar.gz
wget http://static.rust-lang.org/dist/2015-02-08/rustc-nightly-i686-unknown-linux-gnu.tar.gz
tar -xf rustc-nightly-i686-unknown-linux-gnu.tar.gz

RUST_BACKTRACE=1 LD_LIBRARY_PATH="rustc-nightly-x86_64-unknown-linux-gnu/lib" ./rustc-nightly-x86_64-unknown-linux-gnu/bin/rustc --target=i686-unknown-linux-gnu -L rustc-nightly-i686-unknown-linux-gnu/lib/rustlib/i686-unknown-linux-gnu/lib/ hello.rs

This produces:

This is again resolved by updating the libraries for i686, but a more helpful message would be better.

@alexcrichton this must be the 5th instance of this issue today :(

I suggest we close this - it seems not actionable.

alexcrichton · 2015-04-22T01:51:23Z

I agree, thanks @tamird!
