With the few remaining fixes now landed, we can re-enable the option
-Wunterminated-string-initialization (via -Wextra). Both GCC and Clang
have the required multi-dimensional nonstring attribute support.
Build tested allmodconfig with:
gcc (Ubuntu 14.2.0-19ubuntu2) 14.2.0
gcc (GCC) 15.1.1 20250521 (Red Hat 15.1.1-2)
clang version 20.1.8 (Fedora 20.1.8-1.fc42)
ClangBuiltLinux clang version 21.1.0-rc2
clang version 22.0.0git
