Thanks for your feedback! I know that this prevents the warning, but I can't do 
that. The message is calculated by some method and then returned as a string. I 
then need to raise the exception with the readily build string. If NSException 
had a +[raise:string:] method I would use that, but it hasn't! :-(

I have the same problem with NSLog(). I am again building the message somewhere 
and get it as a NSString. I then simply want to log it out and get the above 
warning. 

   NSLog([localException description]);   

That's simply annoying! :-( Isn't there some compiler switch that could be used 
to suppress these kind of warnings?

Thanks a lot,

 Andreas
