I am developing a iPhone app and everything works fine so far. I can build and start the app in the simulator. But when I now start the app with Instruments I got the error:
Try removing all of the frameworks that you are linking in your Target one at a time (and presumably also removing any code that relies on those frameworks). I found that having either CoreVideo or CoreMedia linked with a Target you were building for the iPad simulator caused a crash with this message.
I just got this error and it was a red herring, the actual problem was an Assertion failure. Tracked it down by add an Xcode 4 breakpoint on all exceptions. http://www.dosomethinghere.com/2011/04/18/xcode-4-exception-breakpoint/
I think you're linking against the Security.Framework and possibly libcurl. Try starting a new default project and see if you can compile it without this error.
