FWIW, this is a reproducer from Clang 13 where we still allowed large widths: https://godbolt.org/z/hvzWq1KTK Repository: rG LLVM Github Monorepo CHANGES SINCE LAST ACTION https://reviews.llvm.org/D122234/new/ https://reviews.llvm.org/D122234 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
