title: Crash app with CocoaPods on some devices
body: <p>I added pods to my application and it started crashing on some devices. I made holloworld project with the same result. This is the my Podfile: </p>
  
  <pre><code>platform :ios, '7.0'
  source 'https://github.com/CocoaPods/Specs.git'
  #pod 'SHOmniAuth',    :git =&gt; "http://github.com/seivan/SHOmniAuth", :branch =&gt; :develop
  pod 'SHOmniAuthFacebook'
  pod 'SHActionSheetBlocks'
  pod 'SHAlertViewBlocks'
  pod 'SHFastEnumerationProtocols'
  pod 'authorizenet-sdk'
  </code></pre>
  
  <p>I made 'pod install', 'pod update'. Can somebody tell me where is a problem? If I install ad hoc on my mac everything is ok. If I install on other PC I have crash. </p>
