  7.  
  8.  
  9. There are two bugs in the b5.1 version of swais that make it unusable.
  10.  
  11. The first bug caused a segmentation fault the first time a status message
  12. was printed if the code was compiled with a non-ANSI compiler (Sun's cc,
  13. for instance).  The second bug prevented any useful results  from being
  14. returned (as the number of documents requested was 0!).
  15.  
  16. Here's a context diff for the code:
