cjdb added a comment.

Thanks for getting around to this! Just a nit and a clarifying question.



================
Comment at: clang/include/clang/Basic/DiagnosticSemaKinds.td:821
+  "'%0' will always overflow; destination buffer has size %1,"
+  " but the source string has length %2 (including null byte)">,
+  InGroup<FortifySource>;
----------------
Nit: s/null/NUL


================
Comment at: clang/lib/AST/ExprConstant.cpp:15737
+
+    // Fall through to slow path.
+  }
----------------
This comment is slightly different to the RHS: does that mean that a diagnostic might not be issued?
