Openssl does some muckery with signal masks on ppc (and a few others archs, but not x86), but I don't immediately see it conflicting with our code: https://github.com/openssl/openssl/blob/master/crypto/ppccap.c#L275 It should also already have been executed by the time we accept connections, due to the __attribute__ ((constructor)). I didn't check where netbsd gets libcrypto and whether it does something different than upstream openssl... Greetings, Andres Freund
