Test failure on 32-bit Intel-compatible architecture

While building on the 32-bit Intel compatible architecture ('i386'), we see this test failure:

======================================================================

I noticed that Gentoo is skipping the test: https://bugs.gentoo.org/773979

Can you advise if this test should be skipped? Or does it highlight a real problem with python-zstandard on the 32-bit Intel architecture?

Inizia con tests/test_data_structures.py e test_estimated_compression_context_size, quindi esegui il test fallito su una build compatibile Intel a 32 bit. Confronta la differenza di dimensione riportata con il valore previsto dal test e determina se l’implementazione o l’assertion specifica dell’architettura è errata; il lavoro è completato quando si è deciso tra una correzione e uno skip esplicitamente giustificato.
