iOS App crashing before entering main() with Xcode 4.2 & iOS 5

Question

Background

After upgrading xcode4.1/ios4 to xcode4.2/ios5 I am experiencing crashes while the App is loading and before it even enters main().

Answer 1

I seem to remember having had a similar crashing bug prior to main() being called and I tracked it to a mismatch between IBOutlets declared in app delegate vs in my nibs. Go through and check your outlets to see if any are somehow misconfigured.
