Bug in NSPredicate _evaluateLeftValue:rightValue:object implementation

[Mathias Bauer]

Hi dear list members,

I came across the following code in NSPredicate.m:

( it's in
- (BOOL) _evaluateLeftValue: (id)leftResult
                 rightValue: (id)rightResult
                     object: (id)object
line 968ff.)

>                                 range: range] == NSOrderedSame ? YES : NO);
>         }

IMHO there needs to be a check whether rightResult is longer than 
leftResult, as in this case NSMakeRange will throw an exception.
