bug in sort 5.2.1

[John_Susko]

I have found what appears to be a bug in gnu sort 5.2.1, under Linux.
The attached file is in UNIX format (no carriage returns).  It is -not-
in sorted order.  Running 'sort sort.txt' produces output in the same
order, ie unsorted.  If you have trouble reproducing this, please get
back to me and I'll provide complete environmental information.  Thanks
for your attention.
