Bug#1108776: rust-utf8-width: autopkgtest regression: NotFound, message: "No such file or directory"

[Paul Gevers]

Source: rust-utf8-width
Version: 0.1.5-1
Severity: serious
User: debian...@lists.debian.org
Usertags: regression

Dear maintainer(s),

Your package has an autopkgtest, great. However, it fails since May 2022. Can you please investigate the situation and fix it? I copied some of the output at the bottom of this report. The release team has announced [1] that failing autopkgtest on amd64 and arm64 are considered RC in testing. More information about this bug and the reason for filing it can be found on https://wiki.debian.org/ContinuousIntegration/RegressionEmailInformation

With my Release Team member hat on I allow you to tag this bug as trixie-ignore if this is nearly completely a test issue as it's so late in the freeze and it's not worth removing the package from trixie because of a failing test at this moment unless it exposes a much bigger issue. Having said that, if this is a test only issue and a fix is possible without fully removing the autopkgtest and without making the test superficial, it's still welcome, but it would need to happen soon. 29s called `Result::unwrap()` on an `Err` value: Os { code: 2, kind: NotFound, message: "No such file or directory" } 29s at /usr/src/rustc-1.85.0/library/std/src/panicking.rs:692:5 29s at /usr/src/rustc-1.85.0/library/core/src/panicking.rs:75:14 29s at /usr/src/rustc-1.85.0/library/core/src/result.rs:1704:5 29s at /usr/src/rustc-1.85.0/library/core/src/result.rs:1109:23 29s at /usr/share/cargo/registry/bencher-0.1.5/macros.rs:49:13 29s at /usr/src/rustc-1.85.0/library/core/src/ops/function.rs:250:5 29s note: Some details are omitted, run with `RUST_BACKTRACE=full` for a verbose backtrace.
