`tests/hazmat/primitives/test_pkcs7.py::TestPKCS7SignatureBuilder::test_sign_byteslike` crashes: unsafe precondition(s) violated: slice::from_raw_parts requires the pointer to be aligned and non-null, and the total size of the slice not to exceed `isize::MAX` about cryptography

This issue is only reachable via tests so we're not going to issue a new release at the moment, but thank you very much for catching this @mgorny! We're also adding a new build to our CI matrix to catch this type of issue in the future and I'll send a backport momentarily so that when we do ship 43.0.1 the fix will be there 😄

Thanks. I'm able to verify, it's an issue in rust-openssl, so I'll send a PR to fix there momentarily.
