I tested this on my amd64 snapshot and works fine. Regression test finished successfully. Ran 64 tests in 20.149s I also checked benchmark test. $ python3 setup.py benchmark running benchmark 1000 signatures and verifications with curve P192 took 3.19 seconds 1000 signatures and verifications with curve P224 took 3.84 seconds 1000 signatures and verifications with curve P256 took 5.01 seconds 1000 signatures and verifications with curve P384 took 9.35 seconds 1000 signatures and verifications with curve P521 took 16.25 seconds 1000 signatures and verifications with curve W25519 took 4.84 seconds 1000 signatures and verifications with curve W448 took 12.11 seconds 1000 signatures and verifications with curve secp192k1 took 3.17 seconds 1000 signatures and verifications with curve secp224k1 took 3.91 seconds 1000 signatures and verifications with curve secp256k1 took 4.85 seconds 1000 signatures and verifications with curve brainpoolP160r1 took 2.36 seconds 1000 signatures and verifications with curve brainpoolP192r1 took 3.15 seconds 1000 signatures and verifications with curve brainpoolP224r1 took 3.84 seconds 1000 signatures and verifications with curve brainpoolP256r1 took 4.86 seconds 1000 signatures and verifications with curve brainpoolP320r1 took 6.92 seconds 1000 signatures and verifications with curve brainpoolP384r1 took 9.40 seconds 1000 signatures and verifications with curve brainpoolP512r1 took 15.78 seconds ok inoguchi@
