When i build my app with any optimization level other than -o0, the application crashes at some point because of EXC_BAD_ACCESS. I tries all possible optimization levels (-o1/2/3/s) and all crashes the application.
The compiler is LLVM 3.0.
Any idea why it happens? Is this some known issue?
I would check for uninitialized variables as a possible cause. The different settings causes things to move around and something that is “safe” in the unoptimized build could hold a stale pointer in another.
