Missing check for nullptr in Linker.cpp

Missing check for nullptr in Linker.cpp

Questions & Answers
Description

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.
