byte_copy() reads past the end of the sockaddr structure because it isn't sufficiently large enough to handle sockaddr_in6 addresses resulting in undefined behavior. armv6-alpine-linux-muslgnueabihf-gcc 5.1.0-r0 generates the "UDF" instruction in this case, causing programs to SIGILL.
Ah, good catch. sockaddr used to work, but it's stricto sensu incorrect - and musl is very touchy with standards. I believe the right fix is to use sockaddr_storage, though. I'll commit a fix tomorrow. Thanks ! -- Laurent
