Description of problem:
This bug is exactly like the closed bug 25519 for i386.

I am running RedHat 7.1 on Compaq DS10L boxes (alphaev6 arch).  Whenever I
start rstatd and then query with 'rup localhost' the daemon crashes.  Below
you will find an strace of the running rpc.rstatd process as well as the
contents of /proc/stat and /proc/loadavg.  I upgraded to the rawhide RPM of
rusers/rusers-server (0.17-12) and it still exhibits the same behavior.
