It happens if another LSM other than SELinux is in use.  For
example, the default under Ubuntu is AppArmor.  Since
we do have the same file under /proc used for getting the security
context of a process :
bruno at xenial:~$ cat /proc/self/attr/current 
unconfined

then *pid_context will be not NULL, but "unconfined".  I
