Details from swiftlang#1271 > Amazon Linux 2 and CentOS 7 have a glibc that doesn’t support `posix_spawn_file_actions_addchdir_np` and thus `TSCBasic.Process` can’t launch a process on these platforms with the working directory set. We currently fall back to launching the index tasks without a working directory on these platforms, which I think is fine because SwiftPM gives us compiler arguments with absolute paths. But we should figure something out. > > Using `Foundation.Process` is not an option because it runs `chdir` on the current process for Posix platforms, which is racy if there are multiple subprocesses being spawned simultaneously. On Windows `TSCBasic.Processs` uses `Foundation.Process` and `Foundation.Process` properly set the working directory of the subprocesses on Windows, so Windows is not a problem. rdar://127797048
