LGTM with green CI. Can you file a Github issue to figure out the issue and we can add it in a comment here. That way we can go back to the much more readable variant once the bug is fixed.

But in the meantime, we should make sure that LLDB works properly with the version of libc++ we'll include in LLVM 21, so I think it makes sense to land this change and cherry-pick it.
