bcrypt 4.0.0 test failure on 32bit arch

Tests fails due to a segfault on 32bit Mageia Cauldron, the development version of the distro. I can reproduce the issue also with Fedora 36 bcrypt mock build. Mock is a tool for a reproducible build of RPM packages.

ERROR:   py310: commands failed

Full build logs available in Fedora COPR, mageia-cauldron-i586 builder-live.log.gz.

Reproduce the failure with the 32-bit Mageia or Fedora Mock build, then inspect bcrypt/init.py around kdf and tests/test_bcrypt.py at test_kdf. Run the reported tox py310 test environment and compare behavior on a 32-bit system. Done means the test suite completes without a segmentation fault on the affected architecture.
