AttributeError: dlsym failed 2

Riproduci il problema con rustpython -V e rust-xonsh --no-rc --no-env, poi inizia da __getattr__ e __getitem__ in crates/pylib/Lib/ctypes/__init__.py, seguendo il traceback fino alla ricerca di dlsym non riuscita. Il lavoro è completato quando il comando xonsh non solleva più AttributeError: dlsym failed durante l’avvio del prompt.

I've faced again with https://github.com/RustPython/RustPython/issues/6510

rustpython -V
Python 3.13.0alpha (heads/master:6ff7b3ed2

rust-xonsh --no-rc --no-env
