-S option segfaults

[Franck Lombardi]

Fix the bug 143127 in Debian bug tracking system :
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=143127

PS :    Akim, is it the good patch format to this ML ??
        To make it, I used "cvs diff -u ChangeLog lib/psstat.c", but the 
ChangeLog      
diff is not as your.
        In your patches, you do not have lines "======", "RCS file .....", etc 
in 
ChangeLog entry.
