@phosek Where can I find more information about the test execution? I want to know the platform, architecture, compiler...

I tried to execute the same command (with the latest llvm and polly) several times, but none of them produce this error.

@Meinersbur Do you have any idea about why it could fail or how to debug this problem 🤔 ?
