In both cases, you're malloc'ing one byte too little. You need to malloc
enough space to hold the string plus the terminating null byte:
os_version = malloc(1 + strlen(host_uname->release));
system_os = malloc(1 + strlen(host_uname->sysname));
You got lucky on the first malloc, in that the memory location where the
null byte was written apparently didn't break anything.
