Description of Problem:    
Cvs (client side when using pserver) is crashing if the .cvspass  
file is not accessible.  
   
Version-Release number of selected component (if applicable):    
cvs-1.11.1p1-7   
   
How Reproducible:    
The easy way is to change the HOME environment variable to a  
non-existent or unreadable directory. Then try any cvs  
command that tries to access a pserver.  
  
Same thing has happened when I tried a cvs command from  
sudo (it does not change $HOME, so the target user cannot 
access .cvspass). 
  
    
Actual Results:  
    Segmentation fault (core dumped)  
  
Expected Results:    
    (error message)  
    
Additional Information:  
  The problem is in cvs-1.11.1p1-cvspass.patch (fromn the RedHat SRPM):  
+       fp = CVS_FOPEN (passfile, "w");  
+       fclose (fp);  
  If the fopen failed then the fclose will segfault.
