Not sure if you met the same problem with me. In our downstream, we did a workaround like:

  if (Context.getLangOpts().CPlusPlusModules &&
        To->getOwningModule() != From->getOwningModule())
      return false;

We workarounded the problem by inserting the above checking in `inheritDefaultTemplateArgument()` in ASTReaderDecl. Hope this helps.
(I understand this is not a good solution)
