For several days the App Store has sometimes been pushing out corrupted binaries, prominent developers are complaining. Instapaper creator Marco Arment notes that affected apps will crash automatically on launch every time, even after deleting and reinstalling, so long as the broken file is hosted on the App Store. Just under two dozen apps -- including Instapaper -- are known to have been impacted, though the number may be higher. Fixed binaries should now be appearing, but still require people to delete and reinstall their malfunctioning apps.
