--- Comment #1 from Paolo Carlini <paolo.carlini at oracle dot com> --- The rationale for the change is here: https://gcc.gnu.org/ml/gcc-patches/2018-08/msg00623.html I my experience, accepting such kind of code is really dangerous, because -fpermissive isn't fine grained thus in some cases users want to pass it to allow for other *safe* legacy constructs. That said, clarified that I vote NO, NO based on real, hard, experience, it's the front-end maintainers call, reverting the change would be trivial.
