'sort' bug

[Mike Markowski]

I think I've come across a bug in 'sort'.  Using the attached file (please let 
me know if the attachment is stripped from this email), I tried to sort on the 
5th column of states/countries by using:

   sort -k 5 c3

The first few lines look like:

   10-Apr-2008  W7GVE        729C Ed         AZ             10.120
   18-May-2008  W1GUE        1998 Ed         NH              7.055
   28-Apr-2008  KG4W        2416T Ed         VA              7.055
   11-May-2008  K4ZGB        796T Tom        AL              7.055
   16-May-2008  9A2VJ        2533 Vel        CROATIA        14.052
   [...]

already not properly sorted by state/country.  Also, doing:

   sort -k 6 c3

incorrectly yields:

   23-May-2008  VA5CW        4326 Bill       SASKATCHEWAN   14.055

Yet, doing:

   sort -n -k 6 c3

works as expected.

It could be that the program is working fine and I'm simply expecting the wrong 
result.  If so, apologies!  Otherwise, I hope this helps you pinpoint the bug.

Thanks!
Mike
