When looking through my logs today, I noticed unaligned traps
cause by /usr/bin/who
Upon running it, it seg faulted. I then ran it through gdb to
gain the following:

(gdb) run

This is RedHat 5.0 for the alpha, with all relevant patches up
until about a week ago. It is running 2.0.35, has a 143 day
uptime, glibc RPM version 2.0.7-19. The machine itself is a 166
Multia.
Has anyone else seen this? Is this fixed in the 'who' that ships
with 5.1?
