@Michael137 We've been seeing the LLDB tests that we run as part of libc++'s bootstrapping build fail for a few days (~5 days roughly). This is an example error: https://github.com/llvm/llvm-project/actions/runs/15086636371/job/42430861883?pr=140379. Does this ring a bell? @philnik777 tried reproducing locally (outside of the Docker image) and couldn't reproduce. Have you seen this kind of error in your CI setup before?
