Hi @MaskRay,

I think that the addition of `ctx.internalFile` has broken this statement from `class InputSectionBase`:
```
// The file which contains this section. Its dynamic type is always
// ObjFile<ELFT>, but in order to avoid ELFT, we use InputFile as
// its static type.
InputFile *file;
```

Which can then subsequently cause assertion failures in:
```
template <class ELFT> ObjFile<ELFT> *getFile() const {
  return cast_or_null<ObjFile<ELFT>>(file);
}
```

This is happening in our downstream port of `lld`, although I haven't yet figured out why we are only hitting this code path.
