Do you expect any other sections to be order sensitive? Or just `__eh_frame`? If so we can just explicitly block it and avoid increasing the size of the struct.
```suggestion
      if (sec->name == section_names::ehFrame && sec->segname == segment_names::text))
        continue;
```

Sorry for realizing this so late.
