But what you > suggest seems to be what Clang++ is doing: Although GCC is still much slower than Clang for Steven's original testcase, so the above wouldn't be a complete fix. And the long lines are very ugly. Perhaps there is a way to summarize such a recursive template instantiation. Still, making the "error: template instantiation depth exceeds maximum" a fatal error seems a good idea to me. Jason?
