            Bug ID: 42092
           Summary: [CGCXX] Destructor crash when program memory space has
                    larger pointers than p0
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal

Was crashing due invalid cast on simple c++ code where program memory has 32
bit pointers and default 16 bit.

Constructors in CodeGenModule.cpp are initialised as such:

llvm::Type *CtorPFTy = llvm::PointerType::get(CtorFTy,
      TheModule.getDataLayout().getProgramAddressSpace());

But destructors in CGCXX as:

llvm::PointerType *AliasType = AliasValueType->getPointerTo();
