--- Comment #22 from Manuel López-Ibáñez <manu at gcc dot gnu.org> --- (In reply to Volker Reichelt from comment #18) > The first error message about exceeding the maximum template instantiation > depth appears rather quickly. So maybe we could make the first error message > a fatal one to avoid further processing of potentially bogus nested classes. This is a patch doing exactly that: https://gcc.gnu.org/ml/gcc-patches/2014-08/msg01709.html However, I probably won't have time until the Christmas holidays to work on it, so please anyone feel free to take it and get it reviewed and applied. Thanks!
