Make sure this testcase keeps crashing with -O3. Recent optimization improvements made LLVM realize the store-to-null was unavoidable, so it deleted all of main() and replaced it with 'unreachable'. Because the body of main() no longer even contained a return instruction, calling it caused random code to be ran instead. This happened to be the code that links in the ModuleInfo on my machine, which then returned "successfully".
