Copying the same binaries to real hardware results in success. - -```c -#include <stdlib.h> -#include <ifaddrs.h> - -int -main (void) -{ - - struct ifaddrs *ifa = 0; - int error; - - error = getifaddrs(&ifa); - if (error || !ifa) - exit(1); - else - exit(0); - - return 0; -} -``` -Steps to reproduce: -1. Compile the above program and link it with musl libc (pre-built toolchains are available [here](https://musl.cc/)) -2. Run the appropriate `qemu-*` (e.g. `qemu-m68k ./test` or `qemu-ppc ./test`) -3.
