title: How to find the cause of a malloc "double free" error?
body: <p>I'm programming an application in Objective-C and I'm getting this error:</p>
  
  <blockquote>
    <p>MyApp(2121,0xb0185000) malloc: &ast;** error for object 0x1068310: double free<br>
        *** set a breakpoint in malloc_error_break to debug</p>
  </blockquote>
  
  <p>It is happening when I release an NSAutoreleasePool and I can't figure out what object I'm releasing twice.</p>
  
  <p>How do I set his breakpoint?</p>
  
  <p>Is there a way to know what is this "object 0x1068310"?</p>
