This needs a testcase. It is used by llvm-objdump/COFFDump.cpp, so it should be easy to add one.

lib/Object/COFFObjectFile.cpp

 std::error_code ImportDirectoryEntryRef::getName(StringRef &Result) const {
   uintptr_t IntPtr = 0;
   if (std::error_code EC =
-          OwningObject->getRvaPtr(ImportTable->NameRVA, IntPtr))
+          OwningObject->getRvaPtr((ImportTable + Index)->NameRVA, IntPtr))
     return EC;
   Result = StringRef(reinterpret_cast<const char *>(IntPtr));
   return object_error::success;

     const import_lookup_table_entry32 *&Result) const {
   uintptr_t IntPtr = 0;
   if (std::error_code EC =
-          OwningObject->getRvaPtr(ImportTable->ImportLookupTableRVA, IntPtr))
+          OwningObject->getRvaPtr((ImportTable + Index)->ImportLookupTableRVA, IntPtr))
     return EC;
   Result = reinterpret_cast<const import_lookup_table_entry32 *>(IntPtr);
   return object_error::success;
