+// These functions enable C library runtime hooks to try to catch cases where
+// C++ object addresses remain in hash table of valid wrappers when the address
+// is passed to free.  The hooks are probably not thread safe and thus
+// should only be enabled in single threaded environments
+
+// To enable the hook, uncomment the following define.
