There is no need to copy the data extractor. It contains no modifiable state as the position curser is passed in as variables when acessing the data within. I would highly suggest changing to:
```
const DataExtractor &ProcessElfCore::GetAuxvData() { 
  // Feel free to add asserts here if you want them as long as the code functions correctly
  // even if the asserts get triggered.
  return m_auxv; 
}
```
