title: Showing Leak in Instrument
body: <p>I have developed a function</p>
  
  <pre><code>- (NSMutableDictionary *)characterRangeMappings {
  
          if (!characterRangeMappings) {
          self.characterRangeMappings = [[NSMutableDictionary dictionary]autorelease];
      }
      return characterRangeMappings;
  }
  </code></pre>
  
  <p>If I don't use autorelease it shows a leak in Instruments but no leak showing when checking using analyze (command + shift + B) and when I use autorelease then leak will showing while analyze(command + shift + B) but no leak showing in Instruments.</p>
  
  <p>How I will solve this issue?</p>
