Hi @rastogishubham thanks for acting on this! The log of this particular run was deleted already, but https://green.lab.llvm.org/job/llvm.org/view/LLDB/job/as-lldb-cmake/13958 likely failed for the same reason:

Apparently, `/U` is an option for the clang `cl` mode driver and this collides with the start of the file name path in `/Users/...`. Let me prepare a patch for it.
