@Flamefire Can you clarify why it's fine to disable these tests, and when it's necessary (in which context do these fail)?

We've found the sanitizer tests to be flaky and disable them in other LLVM ECs as well. It is failing in e.g. easybuilders/easybuild-easyblocks#3881 (comment)

It seems to depend on the kernel and ASLR
