iOS App with Static Lib ALWAYS crashes on Launch of Ad Hoc Archive Build. Cant reproduce in Xcode Debugger

Question

We have an App built with a static Lib we are also building for distribution. The App and Lib run fine in Xcode debugger or when loaded on the device by Xcode debugging sess

Answer 1

I had a similar problem and tried changing the project build settings, but it didn't work for me. Eventually solved my problem by changing the compiler optimization level setting for the release:

In Build Settings, go to the LLVM compiler 4.2 - Code Generation section, look for the Optimization Level option and change the Release setting from Fastest, Smallest [-Os] to None [-O0].

Hope this helps!
