Here's the output of version 1.22:

Both versions of sort were run on the same machine, bound to the same
DSO versions:
% ldd /bin/sort
 libc.so.6 => /lib/libc.so.6 (0x4001c000)
 /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
% ldd /r/bin/sort
 /lib/libNoVersion.so.1 => /lib/libNoVersion.so.1 (0x40015000)
 libc.so.6 => /lib/libc.so.6 (0x4001e000)
 /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

The machine is a Redhat 6.1 running with the 2.2.18pre15 kernel:
% cat /proc/version
Linux version 2.2.18pre15 (address@hidden) (gcc version egcs-2.91.66
19990314/Linux (egcs-1.1.2 release)) #2 SMP Wed Oct 11 04:44:56 PDT 2000

Please respond if you are or are not going to look at this bug.  If you
are not, but
could give me a pointer to the source, I'll take a look.
