title: iPhone Memory Error - when using Build & Debug, How to debug?
body: <p>I'm a newbie and need some help with an iPhone App running on the Simulator. The app works fine running with Build &amp; Run or Build &amp; Run - breakpoints off, but blows when running with Build &amp; Debug - Breakpoints on. Any help or thoughts would be greatly appreciated. Lon </p>
  
  <p>Specifics: No breakpoints set, never gets to any visible simulator results, seems to blow during initialization phase before it can generate any output. Source of app is the DrinkMixer example, in the "Head First iPhone development" book (example built up to page 280) by Dan &amp; Tracey Pilone.</p>
  
  <p>Blows With this Error Message:</p>
  
  <pre><code>Attaching to process 970.
  Pending breakpoint 1 - "*0x01c1b001" resolved
  Program received signal:  “EXC_BAD_ACCESS”.
  No memory available to program now: unsafe to call malloc
  Data Formatters temporarily unavailable, will re-try after a 'continue'. (Not safe to call dlopen at this time.)
