Hi,
I am trying to build python tot (https://github.com/python/cpython) using clang tot (https://github.com/llvm/llvm-project) but ran into the following issue. The same happens for 12.x release branch. Does not happen for 11.x.
Let me know if you need more information
Platform:
clang version 13.0.0 (https://github.com/adityaatluri/llvm-project.git ecdae5df7da03c56d72796c0b1629edd0995548e)
Target: x86_64-apple-darwin20.3.0
Thread model: posix
InstalledDir: /Users/aditya/.local/llvm13_x86_64/bin
I am getting the following error:
