@kinke created dlang/dmd pull request #13075 "[stable] Fix Issue 22310 - Cache
failed template instantiations" fixing this issue:

- Fix Issue 22310 - Cache failed template instantiations

  Semantic is re-run anyway for error messages in case errors were
  gagged for the first instantiation but aren't gagged for the current
  instantiation, see line 5645.
