[Balázs Benics via Phabricator via cfe-commits]

steakhal added inline comments.


================
Comment at: clang/lib/Analysis/UnsafeBufferUsage.cpp:54-55
+  bool TraverseDecl(Decl *Node) {
+    if (!Node)
+      return true;
+    if (!match(*Node))
----------------
Can `Node` be ever null if the visitor is initiated only be `AST_MATCHER_P`?
