Suddenly unusable on CircleCI "machine" VMs

Describe your issue

I use CircleCI to run cross-compile jobs using cross for Geph. To avoid the complications of docker-in-docker, I've always used the "machine" class, which spins up a full virtual machine.

Recently, my build scripts have suddenly started failing with this error:

#!/bin/bash -eo pipefail
cross build --release --locked  --target armv7-unknown-linux-musleabihf
Error: 
   0: Ctrl-C error: Ctrl-C signal handler already registered

Exited with code exit status 1
CircleCI received exit code 1

This happened even though the cross utility did not change versions, and my build script did not change. I suspect it's some issue with the docker container itself; it looks like some conflict with whatever code handles "ctrl+c" gracefully shutting down the docker container, conflicting with a signal handler that circleci attaches, possibly to handle the "stop compile" button.

What target(s) are you cross-compiling for?

There was a change recently in the ctrlc crate

Detegr/rust-ctrlc#97

Detegr/rust-ctrlc@7a23454

I'm not sure what we can do about this.
Maybe we can make this a soft error?

For now, install cross with cargo install cross --locked to ensure the versions you use are the same as they were during publication.

[Emilgardis]

This is not fixed on 0.2.5 unless you use --locked to install

@Emilgardis any chance you can release new docker images with this fix?

[Emilgardis]

I'm not sure I understand the request @ekampf the images for the main branch are rebuilt weekly https://github.com/cross-rs/cross/actions/runs/5019408894 currently we have some images failing though, need #1208

the fix is not in the docker images, it's on the CLI tool
