At line 610 in Linker.cpp, the following declaration is made:
UPackage* FilenamePkg = (ExistingPackage ? ExistingPackage : CreatePackage(nullptr, *PackageNameToCreate));
     if (FilenamePkg != ExistingPackage && (LoadFlags & LOAD_PackageForPIE))
     {
         FilenamePkg->SetPackageFlags(PKG_PlayInEditor);
     }
FilenamePkg is used and then later tested against nullptr, although CreatePackage can return a nullptr if a null or "none" name is provided.
