I don't *know*, but I have two educated guesses that it is intended. GCC compatibility (GCC also has this behavior) and the relationship between zero-sized array members and flexible array members. Clang allows a flexible array member to be used in a structure with no members and it behaves the same as a zero-sized array in a structure with no members: https://godbolt.org/z/Gx7ozxYKz Repository: rG LLVM Github Monorepo CHANGES SINCE LAST ACTION https://reviews.llvm.org/D114080/new/ https://reviews.llvm.org/D114080 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
