Building on swift-6.0-DEVELOPMENT-SNAPSHOT-2024-07-19-a causes a concurrency error

Not sure if this is an error in this build of Swift 6.0, but I'm getting errors about stderr not being concurrency safe:

Building for debugging...

My project is on the latest release of swift-issue-reporting:

{
      "identity" : "swift-issue-reporting",
      "kind" : "remoteSourceControl",
      "location" : "https://github.com/pointfreeco/swift-issue-reporting",
      "state" : {
        "revision" : "926f43898706eaa127db79ac42138e1ad7e85a3f",
        "version" : "1.2.0"
      }
    },

I'll try to downgrade to the previous release and see if that had the same issue. But, thought I'd let you know. Also, my project is using the latest swift-tools-version:

// swift-tools-version: 6.0
// The swift-tools-version declares the minimum version of Swift required to build this package.

Hi @xtremekforever, this was fixed in #93 and will be released later today.

Okay sweet! Sorry I did not notice that it had been fixed already- I only checked the closed Issues on this project and did not notice that there was a pull request.
