+
+  The analyzer can generate a hash to identify repots. To debug what information
+  is used to calculate this hash it is possible to dump the hashed string to
+  the stderr of an arbitrary expression using the function above.
+
+  Example usage::
+
+    void foo() {
+      int x = 1;
+      clang_analyzer_hashDump(x); // Hashed string of x on stderr.
+    }
