Some form of check must be placed on the pointers:
```suggestion
  auto binaryVar = dyn_cast<llvm::GlobalVariable>(binary);
  assert(binaryVar && "expected a global variable");
  llvm::Constant *binaryInit = binaryVar->getInitializer();
  auto binaryDataSeq = dyn_cast_or_null<llvm::ConstantDataSequential>(binaryInit);
  assert(binaryDataSeq && "expected a valid initializer");
```
