Contributor guide
Research direction
Start by reproducing the provided Python snippet on Windows and Linux, focusing on the pairing and multiply entry points. Investigate why the Windows process exits with status code -1073741571 and compare the execution path with the working platform. Done means the example completes without an unexpected process exit on Windows, with the behavior verified against the reported case.
