@eliotmiranda have a look at [squeak-app](https://github.com/squeak-smalltalk/squeak-app). `prepare.sh` is the entry point and the builds fail [here](https://github.com/squeak-smalltalk/squeak-app/blob/d7cc75c4e7c9875c7eb5167e...). All files that are needed are in that repository. It's basically calling out to [smalltalkCI](https://github.com/hpi-swa/smalltalkCI) which then runs all SUnit tests with a [few exceptions](https://github.com/squeak-smalltalk/squeak-app/blob/d7cc75c4e7c9875c7eb5167e...). Otherwise, download the latest `Squeak-trunk` and run all tests a few times. Eventually, you'll get crashes like this.
