On Apple platforms we don't perform CPU probes. A CPU probe is where we setup a SIGILL handler and try an instruction. If there's a SIGILL then we know the instruction is not available. On Apple platforms, memory gets corrupted when a SIGILL is encountered. We are not sure why. (OpenSSL and Botan stopped doing them, too). The define you are looking for is CRYPTOPP_NO_CPU_FEATURE_PROBES. It is usually set automatically in config_cpu.h. https://github.com/weidai11/cryptopp/blob/master/config_cpu.h#L180.
