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

In my case it was the -objc flag in Other Linker Flags. I had to remove that and it worked like a charm.
