Last night's nightly ICEs on regex crate #34839

steveklabnik · Jul 15, 2016

https://travis-ci.org/steveklabnik/semver/jobs/145070460

error: internal compiler error: ../src/librustc/infer/region_inference/mod.rs:734: cannot relate bound region: '_#0r <= ReEarlyBound(TypeSpace, 0, 'r)

/cc @BurntSushi

(I can try to get a stacktrace later if it's important)

jonas-schievink · Jul 15, 2016

See #34780 and #34791

steveklabnik · Jul 15, 2016

Gah! I should have searched better. It seems like this is a duplicate.

TimNN · Jul 15, 2016

@steveklabnik: I think one of the issues regarding the ICE in the regex crate needs to be reopened:

The regex crate compiles successfully on 2016-07-12 but fails on 2016-07-15
The snipped from #34780 fails on 2016-07-12 as well (and on 2016-04-22 as well, which was the earliest nightly I had still locally installed).

TimNN · Jul 15, 2016

Looking at the stacktrace, I assume this has been caused by #34755 (although I don't believe that #34755 is the root cause).

Ok, thanks for the analysis @TimNN!

Alright, I've been staring at some debug log output (there's lots of it!) and the current progress is that the ice happens when VariantSizeDifferences is processing

enum FindCapturesInner<'r, 't> {
    Dynamic(re_trait::FindCaptures<'t, ExecNoSyncStr<'r>>),
    Plugin(re_trait::FindCaptures<'t, Plugin>),
}

TimNN · Jul 15, 2016

The following code reproduces the issue:

#![crate_type = "lib"]

trait RegularExpression: Sized {
    type Text: ?Sized;
}

struct ExecNoSyncStr<'a>(&'a u8);

impl<'c> RegularExpression for ExecNoSyncStr<'c> {
    type Text = str;
}

struct FindCaptures<'t, R>(&'t R::Text) where R: RegularExpression, R::Text: 't;

enum FindCapturesInner<'r, 't> {
    Dynamic(FindCaptures<'t, ExecNoSyncStr<'r>>),
}

In case it helps anyone, the debug log is available at https://gist.github.com/TimNN/bb6b3a7396d8b8b71899bba4eee231db

I ran into this while trying to install rustfmt using the nightly build on Linux.

Here's the backtrace, should anyone find it useful.
